HTC EVO 4G :: OMJ 2.2 Kernel ROM Installed / Major Drop In Battery Life

Oct 4, 2010

I did unrEVOked 3.21 and applied OMJ's 2.2 netarchy kernel ROM. I am not sure what my battery life was at this point but I was now on 2.2 after using eclair 2.1 for so long. I wanted to go to the new stock kernel so reupdated to OMJ's stock kernel 2.2 ROM. I also added back the Sprint TV Widget. Ever since, I have noticed a major drop in battery life. I usually get 30-40 hours on a single charge. Now I'm down to about 10. It is REALLY screwed up. I have CWM backups of all of the phases, including my 2.1 ROM. I might experiment rolling back if nobody else has any better ideas on how to debug?

I am using ATK but I make ATK kill itself so it is only there to help me kill procs. I noticed QIK and FRING seem to run all the time now whereas they didn't before I updated them. Not sure if that is related. TOP app shows me nothing special but system_server taking up most of the CPU like maybe 6% peaking while idling. Otherwise I just can't figure it out!! I used to be the one bragging about how awesome my battery has been (running original OTA1 which let me still use unrEVOked 1.0 to get simple root all this time). I am finally on 2.2 and I'm disappointed with battery life now. WiFi is WAY better but that is about it. My Nexus One does not suffer from 2.2 battery blues.

Motorola Droid :: Battery Life On ROMs / Kernel

Oct 9, 2010

I have the droid rooted running lfy 1.7. My battery life has been ok but not great. About 10-12 hours of life when I send about 3 texts one or 2 calls and an occasional download. I have also run udx 8.0, cm6, charity, and bugles .5. Udx has about 8-10 hours, cm6 has about 6-8 hours, charity has 10-12 hours and bugless has 5-7 hours. I was wondering what Roms you are using and what battery life you are getting. Please include the kernel, your speed you run at, and your usage.

HTC EVO 4G :: Fresh 3.2 - With Either Netarchy-toasted Or Kings Kernel - Battery Life

Sep 12, 2010

I installed Fresh 3.2 and have used both netarchy-toasted and kings #8 (and9) kernels. With both combinations I've noticed that my battery drops 10-13% over night while i'm sleeping. I looked at Spare Parts and SystemPanel and nothing stands out, no app or service is taking over during that time. I did not have these problems when I was on the stock 2.2 unrooted setup.

HTC Desire :: Battery Life Once Froyo 2.2 Is Installed

Aug 2, 2010

Anyone finding their Desires battery life has decreased with Froyo installed? I used to only go into the orange after a full day at work, now my battery died at around 12 Midday (Unplugged it 5 hours before) - I haven't been playing around on my phone or anything, this is just idle use.

Went through all my settings and all were the same as before. I'm NOT running any Task Killer or AutoSync software. Running stock OTA Froyo, never routed my phone before or after.

HTC Desire HD :: Installed Applications Delete Option Greyed Out (Battery Life)

Oct 29, 2010

Got my nice shiney Desire HD yesterday. First HTC phone, first Android phone. Impressed on so many levels, but also have some questions and one problem.

1. How can I remove apps that are pre-installed like soundhound, talk, stock. The remove option is greyed out.
2. Can I create a sub folder in the menu tree and move like games into one. I have created a sub folder on the home page, but cant rename it from 'folder'
3. My phone picks up WiFi signal at home everytime I am in range. Does this mean WiFi is always on, searching. My experience from my E71 showed me this kills battery. I seem to struggle to get more than 10 hours life from the battery, what gives.

HTC EVO 4G :: MAJOR Battery Drain

Jul 23, 2010

Well, its been about 32 hours with my EVO...and im loving it.

I admit, the battery worries me a bit. However, some commonsense things (and not so common sense, like the GSM/CDMA battery life change) have really helped. Task Manager seems to be the best overall task killer app, and keeping background data on but auto sync off seems to be a nice happy medium for syncing.

The major, MAJOR battery drainer? Google Maps/Navigation. The perfect argument for a car charger that can EVER be made. Ye gods.

So I unplugged it from my charger at 11 this morning. As of right now at 6:43 pm i have 41% battery left, have been fiddling with it for about half of that time, and turned disabled the data connection while i was in low signal areas during a short road trip.

Moderate use of Yahoo Messenger, texting, a few 5 minute phone calls, the occasional manual update of the Seesmic twitter client and a few other things have drained it a little bit...but a 5 minute stretch of Google Navigation? Did the most damage to the battery, knocked it down by 7 percent. Again...car charger. Need this soon. Anyone know of any reliable ones?

Other than that, great phone. Versatile, and I'm looking forward to the day that Android 2.2 comes to us for even more battery efficiency. Please feel free to ask me anything about how I have things set up, constantly trying new things out on this!

So, I've just installed the two Hyra kernels and after checking the "about phone" section, I see the undervolt kernel has been installed. Now I've got a couple of questions.. 1. How do I know the overclock kernel was also installed? 2. Are there any settings or anything I need to turn the kernel "on" or is it automatic?

HTC EVO 4G :: Time To Battery Drop 10% In 4G?

Jul 11, 2010

How much time it takes for your battery to drop 10% when you're on 4G doing no downloads, no streaming, no Youtubing, nothing? In my case just 30 min. Complete discharge in approx 4 hours The temperature is very hot too. Do not put it under the pillow.check it out, this is ultimately just a 30 min test, and post it here (say to voice dialer "Open battery Info" for battery numbers and temperature instead of bars)

HTC EVO 4G :: Battery Doesn't Seem To Have Initial Percentage Drop

Jun 28, 2010

In my case, I think the charger that came with the phone is not charging the battery properly. Last Friday I left the Evo charger at work and had to use a Nokia charger to charge the phone. The usage was the same, but now my battery doesn't seem to have the initial percentage drop and seems to last longer. Also, it charges bit faster (I know this is not great for the battery). Will do more testing.

HTC Incredible :: Battery Drop Down To 90% / 5mins After Unplug

May 6, 2010

Just wanted to get some opinions here about my battery performance to help determine if it's defective and to see if I should return the phone for a new one.Whenever I charge my phone, it gets all the way up to 100% (obviously), but after I unplug the phone the battery will drop down to around a 90% charge level 5 minutes after unplugging it. And that's with no usage at all. I simply unplug it, turn off the screen, and stick it in my pocket. Mobile network is enabled, but bluetooth, wifi, and gps are all off and I don't have any crazy apps running that are draining the battery. Within an hour (with little or no use), the battery will then usually be in the 75% range, sometimes a little lower. I don't think I've made it past 11 or 12 hours yet without the battery dying, even though my usage is pretty light. Any ideas on what is going on? Do you think the battery is just a junky one or is this normal behavior for the phone?

General :: Battery Percentage Drop - Rapidly Decreasing?

Feb 23, 2014

I have a problem with the battery percentage of my device, it drops from 60% - 15% but after i reboot the device it goes back to 60% and rapidly decreasing by 1% per minute until it reaches 1%. Even if it's on 1% the real charge of the battery is still there, it last for almost half a day, i just wanted to know the real charge of my phone. I don't know how to fix this i already tried calibrating but it doesn't work. I also tried using new battery and flashing to stock rom but the problem still exist.

Samsung Captivate :: Anyone Seeing Very Quick 10 Percent Battery Drop Issue?

Jul 21, 2010

Anyone seeing an issue where they charge to 100% percent overnight, pull the phone off the charger and see a very quick drop to 90%?I know the HTC Evo had this problem, and it seems like my phone is doing as well.I charge it all night, pull it off the charger and surf for like 10 minutes and the battery level plummets to 90%.Its interesting to note that if you charge the phone to 100%, turn it off and charge it, the battery indicator will display 90% and take about 10 mins to get to 100%.you then turn it on and charge it, the battery will be at 90% and will take another 10 minutes of charging to reach 100%.This is basically the HTC charging trick. After doing the charge while on/charge while off cycle several time, the battery will truly be at 100%. The problem is, I dont really want to do this every time I charge my phone.

Motorola Droid :: Battery Life - Or Battery Widget

Mar 16, 2010

Background info:

- I'm running the "Battery Left" widget and I have it displaying "estimated percentage left", "system percentage", and "estimated time left until dead".

- I listen to A LOT of Slacker Radio.

My issues:

- I was previously getting about 19+ hours out of a fully charged battery. 2-3 days ago I started having issues with the widget (I think it may have started when I installed an update to the widget) so I recalibrated it to no avail. Then I uninstalled it and reinstalled it. Within a few hours it claimed that it was getting accurate readings (when I first installed the widget weeks ago, it took days to get accurate) and now says that I should be getting 9 hours out of a fully charged battery. I know that can't be right so I'll see how the widget adjusts itself over the next few days, but, any thoughts? (I know a lot of you guys use the same widget and know how it works...)

- Also, In the first two hours of my phone being unplugged this morning, it went from 100% to 70%. I did run Slacker for about an hour and a half of that time, but could it really drain the battery that much that quickly? And I noticed that when I close Slacker, if I go into phone settings, applications, running services - there's still a Slacker update thing running in there. Could that be draining the battery too, even if it's only checking for updates?

- I really don't run a lot of stuff on this phone. I keep wifi and gps turned off. I use bluetooth only a few hours each night. Minimal web browsing. Although, my POP email gets checked every 5 mins (but I just changed it to every 10) and I do use gchat and text a decent amount, but I'd say overall, it's "light" use (except for Slacker which could be a huge drain, right?)

HTC Incredible :: Bad Battery Or Poor Battery Life

Jun 23, 2010

My battery life was bad, but it was OK, but in the past few days my battery life is 10% per 30minutes(Just over 5 hours on a charge).I used to get 8-10 hours on a charge.I noticed last week that while it was charging the status of the battery was "Overheat".I think I somehow cooked the battery?I use TaskKiller and kill 95% of apps automatically, I have bluetooth,wireless,GPS disabled and the screen dimmed.I have not changed or installed any new apps.I have not changed the way I use the phone at all.My battery was dead, 0%, and it charged to 95% in about 45 minutes.Is this even possible?In fact in the past two days I have not gotten the charge above 95% at all.
