HTC EVO 4G :: Cell Standby Demolishes Battery
Jul 29, 2010
I charge my evo while I'm sleeping. Last night I went to sleep with it at 100% and woke up 10 hours later to find that I had lost 50%. Battery indicator told me that it was 48% cell standby and 48% phone idle and only 2% Android system. Is this usual? I didn't know just leaving my phone on the table would kill so much.

Im trying to figure out the consumption issues with my battery and cell standby. it is currently responsible for 39% which is at the top of the list just above phone idle. what really concerns me though is my time without a signal is 49%!! but everytime i look at my phone it has 3bars! how can this be? and im assuming this is whats killing my battery? it should be noted that i dont think i have the "bug" others seemed to have.

I was just wondering if anyone had the same issue as I do, with about 44% of my battery use coming from the notorious call standby.
I heard some speculation that this is akin to the issue with the Eris 2.1, so it would be solved by the Airplane Mode trick, but I have not found any results favoring that remedy.

I tried doing the Airplane trick...I am not sure this is the 50% issue others have mentioned because when I go to view my battery statistics, it doesn't show the 2 lines of information like it did before (i.e, 50%), but my phone idle and cell standby are Both hanging around 36%...seems kind of high in my opinion.

Just yesterday my phone was getting more than 14+ hours of battery. Now it's draining really quickly even when I'm not using it (I left it on while I was asleep). It's not facebook because I already downloading the fix and rebooted. My "time without signal" is 0% so I don't think that's the problem. I did download Quickpedia yesterday but a quick search tells me that's not the problem either.
The only other thing I did differently was switch from ADW to LauncherPro yesterday, but if that was draining the battery wouldn't it be under Android System and not standby or idle? Regardless, I switched back to ADW just to see if that works

I recently purchased this Tablet cum Phone Device (Asus Fonepad) in India. I found this device very impressive with decent battery backup along with great standby time. Everything was allright. In morning I found heavy battery draining during standby.
Next day I uninstalled that Black market application and Uninstalled Exdialer with all downloaded themes. I got full signals and everything was working fine. But the Battery Drain in standby remain same. I observed the situation till next two days. I searched to forums and did following things:
1. I made factory reset to my fonepad. which was haviing 4.1.2 Android after updating through OTA. Which remains same after Reset.
2. I didnt install any other applation
3. I turned of all battery comsuming services like GPS/ Location reporting/ Data/ Wifi/ Uninstalled Google Play Service Updates etc
4. Installed Wakelock detector, Better Battery Stats etc All are showing that phone goes in deep sleep no prblem but Wakelock detector show that Cell Radio wakes up so much time when phone is on sleep mode. Default Battery monitor of Android Showing "Mobile Data" as most battery comsumer.
One thing I want to mention here the device is supportive to mini sim only. I was not having mini sim so I went to market and mobile shop keeper cutted my Sim to adjust into that slot and it woked. I was using same sim from Day first. It's Vodafone INDIA.
I have not rooted nor flashed anything from my fonepad. I am reached to the conclusion that There is some problem with Exdialer installation and applying new/old theme combination to it which made me device with no signal. And now The Cell Radio has been changed which is attempting to achive something in standby mode. Which is causing heavy battery Drain. Standby time is reduced to almost 15-16 Hrous

First off, I read these forums like every day for 2 months (nearly drove my wife insane!) leading up to the release of the X. Stood in line and bought one in the store on the 15th. Had nothing but iPhones until now - loving my DroidX!
BUT
As of right now my battery is down to 60% after having been unplugged (when I unplugged I was at 100%) for 1hr 46m 9s!
It shows display at 93% and cell standby at 7%.
I'm running smart battery mode, auto screen brightness, not that many widgets, and I rooted it and have autokiller running on Aggressive.
Do I just have a bad battery? And if so will Verizon (or Moto) give me a new one?

Does this just mean I am in a bad cell zone? This is my reading at home and it is the top battery usage on the chart, followed by wifi at 24% (on because I am home), and phone idle at 23%.

I know about the 50% without service bug and my phone has it, but I did the airplane trick and I don't have any time without service anymore, but I still have a high amount of time from cell standby. Is there a way to get rid of it? Or is my phone still having a problem? My phone battery will only last about 12 hours, so my battery life has gone up

There has been almost no variation from that. Every now and then Display or Wi-Fi would show up as about 2% each, then disappear after a while. That's all.Last night my battery reached 10%, I turned off the power, charged it overnight for 12 hours, unplugged it, and turned the power back on. I noticed two things:
1. My Battery Use list changed drastically. I assume this is actually a better representation of what the list should look like than what I had been seeing for two weeks, but the other thing I noticed was
2. My battery was draining a lot faster than it ever had during the previous two weeks, even during idle periods.My battery had consistently been draining at around 1% per hour idle until today. Now I'm seeing it drop 5% in LESS than an hour while idle (idle meaning the screen shuts off and I don't use it).
So my question is, what do Cell Standby and Phone Idle mean? Previously they had both been 2% and my idle battery use was excellent. But today they both shot up to the 20-30% range and I'm thinking this may account for the excessive battery drain even while the phone is sleeping.Why would these two things be so high? Nothing changed between yesterday and today except that I turned off the phone and turned it back on. I almost feel like I messed something up by simply turning it off!

I checked to see if I have the cell standby 50% bug and I do. My up time is 11:34:50, my awake time is 3:47:48, but if I look at the cell standby it says time on 14:42:16. How can the cell standby thing be a longer time than my phone has been on? I did the leak 2 days ago, so it's not showing that time or anything.

Is it normal to have phone idle around 31% and cell standby around 34%?

When my phone goes into standby (is that the same as sleep mode, BTW?) is it still connected tothe internet ? If not is there a setting that will automatically disable it (I don't mind manually re-connecting it again)?
I don't have anything auto-synching, so I don't need to be connected while I'm not actually using it. (Just thinking of ways of saving valuable juice )

I usually charge my phone before I go to bed and wake up to it in the morning somewhere between 93% and 97% battery left.
This morning when I woke up I was at 75%. I checked the battery usage history and the "Dialer" used 92% of battery since unplugged.

Just got my Nexus One yesterday, and I'm loving it! My only concern is the battery life meter is telling CELL STANDBY 67%?? When you click on it, it says time without signal 50% and then it says thats whats causing battery consumption.
Before I go on, I have no issues with 3G, been getting a solid signal since I got the phone yesterday, just a little confused on what to do? Shouldn't standby SAVE battery?

This is probably a really dumb question but my battery life info says that the android system is using 96% of my battery and standby and idle are both using only 2%. Is this a good thing or a bad thing? Should my standby time be higher? Or is it better that it is a low number when it is idle/on standby. First smartphone ever here and I just don't know if that is good for my battery or not.

At home i've noticed that even though I have wifi on, it'll drain 15-20% of my battery over night (8 hours). When I turn the display on it'll show that there's no wifi connection available, but wifi is still enabled. After i turn the display on, it'll quickly connect to my wifi. Is this normal? How do i make it stay connected to my home wifi when the display is off/phone is in standby?

I got a DX on the 15th and about a week ago I turned my eris on to check something, well this morning to my astonishment the phone was still on.. Pretty good standby time if you ask me, my razor didn't even last that long...
Lasted over 8 days. I can't post the pic now because I'm on my phone, but I'll upload it later.

For some reason, which I can't figure out yet, when I go to Settings -> About -> Battery and look at usage, my cell standby is always highest which is fine but Bluetooth is always #2! I'm talking on average it's always 25% or close to that.This seems odd because it's just on, not connected to anything. If I turn off Bluetooth it immediately drops (obviously) so it just seems that for some reason the Bluetooth on this phone eats battery life like no tomorrow. What's stranger is WiFi (which I leave on 24/7) hardly goes above 10%.Very odd. Anybody notice the same? I guess I just have to get into habit of turning off BT when I'm not using it.

Heres a question that I couldn't seem to answer by reading the other threads. I just moved up for a small town in the middle of nowhere with modest 3G service, but now that I am in a big city where I have complete 3G all the time my phone doesn't last me more than 3hours even on stand by.

I've a Galaxy and I installed the rom GalaxHero, but last few days my Galaxy uses a lot of battery. Turn On the phone at 13 o'clock, still in standby, at 21 o'clock the battery was at 55%. That is completely abnormal. I've installed the application "spare parts" and I see that in "Battery History" - "Other usage" it reported running 97%. So I Installed another program, "Drain-O-Meter", this brings me to the process "System_Server" which uses the CPU to 100%. The battery lasts me very little, maximum 24 hours in complete standby. Before we even did about 70 hours!

I have a new Xperia Mini which claims to be capable of 200+ hours standby time. I'm getting only 19 hours! I have disabled everything - Navigation, 3G, Wifi, GPS, Updates, but its still draining in less than 24 hours. Can this be right?

When I check what has been using my battery, I see that 32% has been used for "Battery used by cell radio". Does anyone know what that means? Does it refer to the FM radio? Because I made sure that was not turned on.
