Android : Battery - An Hour And 45 Minutes Of Actual Use Out
Jun 16, 2010
I've had my EVO for about a week now and i've been trying to figure out the most efficient way to get a good days worth of battery. Nothing I have done has worked so far, maybe I am missing something. I am only getting about an hour and 45 minutes of actual use out of the phone and its on standby for about 8 hours and needs to be charged. Is this normal? I dont think it is...I installed ATK to see if it would help kill apps that I dont need running, but it didnt seem to change much even on aggressive kill setting. I did have it set to kill whenever the screen turned off, but i just changed it to every half hour. would i benefit from rooting to get rid of Sense UI?

I manually updated my Eris the other night and I must say I am happy with the update, it has really helped with my battery. What I have done is installed Battery Indicator by Darshan Computing. This puts a battery percentage indicator in the notifications area. I have set the built in timer for an hour and when it goes off I make a note of the battery in form of a percentage. Here is what I have so far.
Hour/Percentage of Battery Remaining
1/98
2/85
3/82
4/80
5/77
6-70

Got a really strange problem. I am in Vietnam using MobiFone service. About 3 months ago something changed overnight and my battery went from 20 hours to just a 6 hour battey life. After a week I did a factory reset but the same. Took it to HTC in Saigon to be tested but they said no problem YET when I was there battery lasted longer. The problem was in only in Can Tho where I live UP to this month when the problem is now in Long Xuyen. I travel, to Cambodia a lot and usally when I leave Can Tho Battery life is better. I am now in Cambodia and battery life is 40 hours on a CamShin SIM. For a test in Can Tho I went to a phone shop and used a Vinaphone SIM for an hour and got a 40 hour life. This is a joke! Is there any application that can control the Radio or at least tell me what's going on? I tried a few but they do not say anything different between Vietnam or Cambodia. MobiFone did something but refuse to tell me anything. Back of my G1 with 1.6 is cool now but in Vietnam back of phone is very warm. Tried to reflash the Radio but phone will not let me. I rooted but still it will not let me. think I must load a new recovery program.

When I get up in the morning and take my phone off the charger it's at 100%. Within an hour or 2, it's at around 85% with little to no phone usage of any kind. Wi fi, 4g, gps and all that stuff is always off. Has anyone else experienced this with their Evo? I apologize if there is already a thread on this.

My half year old HTC Magic has problems with loading the battery (non of the LED is lighting up and also the icon does not show that it load.But it loads somehow when I plug it in the loader.It shows after a while that it is 100% loaded.But it unloads in 90 minutes completely.Is this a battery issue or a hardware issue?I also made hard reset, but it did not change a thing.

I propose that we all post our battery life graph like the one I am about to post below. This way we can look at these claims in scrutiny, and perhaps figure out why it is that some people's Evos seem to last longer than others. Here is a graph of my Evo's Battery Charge over 1 day:
Wake up at 7:30am to disconnect the charger, listen to Pandora on the car to work until I arrive at 8am. Idles until lunch time at 12pm. Use the Evo to read up on some news at lunch until 1:30pm. Listen to Pandora while working until 5pm. Drive home while listening to Pandora in the car. Battery starts giving warning indications while driving, and phone dies when I get home at 6pm. Very usual day, and matches what the battery charge graph shows. The top apps of the day are:
System Processes contains mediaserver (2.4% due to Pandora), akmd (0.3% accelerometer polling), and everything else is <0.1%. As you can see I barely used my phone during the day for anything but Pandora. So based on my data, I'd say that the normal battery life for the Evo is under 10 hours. My settings are: no 4g, no wifi, no bluetooth, yes gps, yes bckgrnd data, auto brightness, no live wallpaper, yes taskmanager (ATK, set to "safe" setting. Will probably get rid of this..), no friend stream, no flickr.
I'd love to see other people post up their Battery Usage graphs as well. The App used is "SystemPanel App / Task Manager", available for free in the market. Go into Settings and allow it to Monitor. The screenshots were made by ShootMe, also available in the market.

Managing just 8-9 hrs with ny battery, and believe me I barely use the phone! Just a few calls, few texts, 5 min Internet, 5 min face book - thats it. I have everything turned off that I can turn off. Come on HTC sort it out - this is obviously by far the worst criticism you have.

and I can't figure out what the hell it is? Unplug everyday @ 6:30am, it is now 12:00 noon. Usually battery is around 70 to 80%, but today is @ 50%. I can't figure out what's going on. I don't believe I've done anything much different today than any other day. ETA...I downloaded and installed 2 apps last night from the market...GPS Status (but it and GPS is off) and Microsoft Tag Reader (also is not running).

I don't have any battery issues with my EVO when in idle (<1% drain per hour), and there have been many times when I've charged my phone every other day. However, are there any tricks to increasing battery life when you are actually using the phone such as when web browsing? When I use my phone, it seems to use up battery really quickly...i.e. up to 30%/hour when browsing (tried both dolphin and stock). Similar drains on 3G or wifi. Running Fresh, Netarchy 4.1.9. Used to run Netarchy 4.1.8 with SetCPU profiles and got slightly better battery life. I was told not to use SetCPU with 4.1.9 because of HAVS. Is there something else I can do that is compatible?

The purpose of this discussion is to talk about how applications and usage settings have an impact on standby time. I think we can *all* agree that our Incredible spends more time in idle mode as opposed to actual screen-mashing, voice jabbering, finger pinching usage time. So if one person's battery drops 6% in an hour of standby, and another's only drops 1%, what is the problem? And more importantly, what is the solution?
Standby/Idle: The state of the phone when the screen is off. Pressing the power button brings the device out of standby and all functions are immediately accessible. Phone calls and notifications are possible in standby/idle. Off: The state of the phone when all radios and electrical systems are turned off. Pressing the power button initiates the boot sequence, where one must wait for some time before using the handset................

Does anyone else's battery go as such - full for a bit, then nothing but the nipple gone for half the day, then suddenly what looks like half left out of no where? No matter how much I use my phone. Like I guess I am looking for an "hour-glass" effect here, it should slowly drain until it's empty. I have never seen my battery icon look 3/4 of the way full, it just skips right over that look on my phone.

New DINC owner here, I am somewhat questing if my battery is anygood on my new phone. I unplugged my phone with a 100% charge and the green light on. I made one 4 minute phone call and viewed 4 emails and in that 10 minutes my battery went from 100% to 90%.
Stats are:
Unplugged for 10m 22s
android system 92%
voice calls 4%
cell standby 2%
WiFi 2%
Just viewing the battery use screen brought my phone down to 88%. Is this draining to fast? I also noticed last night at work I walked in with a 100% charge, I played around online a good amount and looked at some apps. Within an hour my battery life was down to about 60%. I realize these phones use a lot of battery but this one seems to be losing it's charge in a real hurry, my Blackberry was no where near this bad.

HTC's looks nice but is only so helpful. Is there a nice app or is it better just to bookmark weather.com or something?

Now that the Hero has been out there for more than a few days, how about a daily rundown of battery life. Day 1: Fully charged to 100% at 10PM. Left on overnight and the next morning was at 78%. Used moderately just trying to figure stuff out and adding a few apps and had 23% by 3:30PM. Day 2 : Fully charged to 100% at 9PM. Turned off. Woke up to 100% at 4:45AM. Used sparingly (3-4 quick 2 min calls, a couple texts, and jumped on web 1-2 times for less than 2 mins ea) and by 4PM had 28%.
Day 3: Charged to 100% at 8PM. Turned off at 10PM with 99% showing. Woke up at 4:45AM with 99% and made a couple quick calls, sent 2 texts before 11AM and was at 78%. Then added 40 contacts to phone and by 2PM it dropped to 38%. By 4:30PM it was on life support at 11%. Day 4: Charged to 100% at 10PM and left on overnight. Started day at 7:45AM with 89%. Used moderately for similar tasks above and now at 3:15PM its at 65%. So there you go. I'm not really happy with the battery life, but this is my first true "smartphone" so it might just be the norm. Seems a bit much to be struggling to keep above 30-40% battery life after only being on for 12 hours.

I found a way to find the actual battery charge while messing around on the phone. I turned off the phone and then pressed the "send + center + end" combination to get into the diagnostics console. From there you can scroll down to the battery info and in there you can see how much charge is really left. For some reason the OS can't read from this and reports incorrect battery life.

Had the phone for around 10 days now and thankfully I am starting to get more and more use out of it, especially after tweaking some settings and what not, and over the past 2 days I am closing in on getting 24 hours from one charge with what I consider fairly heavy use (well heavier than what I used my old Pixon and that needed charged daily). The one thing that is bugging me though is this, I put the phone on charge before I go to bed, I wake up and it is around 90% (give or take a few %). Now I realize that the phones doesn't trickle charge but when I check the drain on juiceplotter, at the same time every morning, it drains.
5am-5:30am it goes down 10% or so, with out fail. It loses the charge in around about half an hour, meaning when I get up in the morning I need to pop it back on charge for a bit to get it back up to 100%. Not a huge hassle but it is irking me somewhat now. When I check programs running etc, there is nothing untoward on the go that isn't on during the day. I half though the phone was not sleeping during this time but after 5:30 the drain stops and it goes back to normal.

This morning I took my evo off the charger after charging the whole night. For some background info I have all my accounts to sync manually and I did the gsm data trick and I am not running a live wallpaper. So I start my phone and turn on my wifi( I have everything else off) I then go watch about 10 mins of youtube videos and check my email. So I started at 100% and at the end of the videos and checking my email I was at 75%! What is going on here? I have done everything I can to ensure proper battery life but this seems outrageous?

I just took my phone off the charger from a full charge. My battery is down 12% with 15 minutes of use. All I did was check emails and this forum. Do I have a bad battery or am I over reacting? I don't want to exchange my phone for another incredible but if I have to I will. Maybe Verizon can swap batteries?

Plain and simple: When the Evo is fully charged, it begins running off its battery until you plug it back in. It DOES NOT trickle charge whatsoever after it reaches 100%. When you're using your Evo on the charger, and it's showing full 100% charge, it is running off the battery, not the AC plug. And then when you unplug it, well, we all know what happens next. The battery meter drops insanely fast to the actual charge of the battery, which could be very low, depending on how long it's been sitting idle at 100% on your charger. So all those times you've charged your Evo overnight, only to take it to work the next day and be at 80% within an hour? Your Evo was running off its battery for what I'm guessing was most of the night. It takes my Evo about an hour to two hours to fully charge back to 100%. Let's say you put your Evo on the charger at 11PM, it'll reach full charge by 1AM at the latest, and then run off its battery until whenever you take it off the charger in the morning. Workarounds? 1) Turn your Evo off while it's charging. 2) If you must leave it on for an alarm clock, put it in airplane mode and end all CPU intensive tasks to minimize battery drain. 3) When you wake up, unplug it for 10-20 minutes (still experimenting with this number), and then plug it back in to top it off. Onceit reaches 100%, take it off the charger, and go about your day. Try it out for yourself. When your Evo is 100% charged, take it off the charger immediately, and I highly doubt you will lose the 10%-15% within minutes.

My battery seems to do alright but one thing that has really been bugging me is that every time my battery gets to 30/20% it dies almost instantly lasting no more than 15 minutes from normal usage (texting, checking email).
Is this normal or is mine a bad battery or a battery gone bad rather? Thing is the battery lasts a long except for the last quarter of the battery. I've never seen my battery hit any values below 20% except 5% which is when it turns off immediately after.Call for a replacement battery or is this normal? Do i have to reset my battery or something?

I have a utility at the top called Battery Indicator reporting the percentage of battery power remaining. I did a test where I would randomly click pages on this site and wait a few seconds on each page, over 3G, and concluded I was losing 1% every 2 minutes. Is this normal or is it comparable to your experience?

I woke up, my phone was at 100% charge. I turned it on to check email/facebook, etc and suddenly noticed that the battery had dropped to 50%. The battery breakdown menu shows that it dropped almost instantly, 82%, my screen which was at the lowest brightness setting. It's a Galaxy S3.

I own a Jiayu G4 Advanced for about a week now and I have been having these weird battery drops. Whenever it reaches about 40%, it drains to about 10% in just minutes. I already tried battery calibration, newer version of the ROM and even a factory reset without result...
