KitKat 4.4 :: Massive Battery Drain When Using USB Tethering

May 25, 2014

I'm having this issue on my Moto G. Sometimes my battery is full or almost (like 95%) and then when I plug my phone via USB to the computer and turn on USB tethering, it appears on the screen a message alerting low battery and it shuts down. Then when the phone is up again, it shows 1% in the battery menu and starts charging again.

General :: Battery Drain On AT&T GS3 With CM 10.1

Aug 10, 2013

For some reason my battery drained extremely fast while it was idle. My phone had about 50% left and an hour later it got all the way down to 14% without any usage. Wifi was on and I didn't get any notifications. I know there are background processes but to have that much battery drained is really strange.

General :: Quickest Way To Drain Battery?

Nov 17, 2011

What's the best (read: most efficient) way to drain the battery? this is after a new kernal or ROM and during a battery recalibration. I'm thinking WiFi off, GPS on, even better, searching for a signal; screen brightness at 100%, no auto dim; lots of apps in task manager; streaming internet video.

I can leave 4G on, with no 4G coverage within 50 miles of me that should suck some more power. I thought the vibration buzzing might be a pretty decent power hog, but a) not sure how to make it stay on, and 2) not sure I could put up with hearing it for that long.

General :: Battery Drain App With Time Log

Sep 16, 2012

Android app that will use a lot of battery (maybe using the phones functions like wifi etc) to drain the battery and then when the battery reaches 1 or 0% it logs how long the battery lasted.

This could then be used to compare battery life on a range of Android devices.

General :: ZTE Grand X In Battery Drain

Apr 11, 2014

There are many battery drain processes, applications. I saw that one of the biggest issues related to my ZTE Grand X In battery drain problems are mostly related to WiFi.

Explanation (all in sleep mode):

- When WiFi is off (and Airplane mode on) battery drain is 0-1 % during 1 hour;
- When WiFi is on (and Airplane mode on) and I am at the home Access Point environment, battery drain is 1-2 % during 1 hour;
- When WiFi is on (and Airplane mode on) and I am outside any Access Point environment, battery drain is 2-3 % during 1 hour;
- When WiFi is on (and Airplane mode on) and I am at an Access Point environment where Android is getting connection but does not get IP address so it is repeating obtain IP address process, battery drain is 4-5 % during 1 hour;

On ZTE Grand X In there is Android ICS 4.0.4.

I am emphasizing that I have Huawei Ascend Y300. It has Android JB, and it is almost not affected at all by mentioned WiFi issues, all the time, in any environment (I mentioned in this post) it has low battery drain.

As I saw there are some programs which are checking those WiFi different situations and then try to resolve issues. For Huawei, I simply do not need any program, everything is okay. For ZTE seems that there is no perfect program, I have to say there are nice programs, but still not perfect for resolving this issue.

What would be the best to do (on rooted Android smartphone) to change frequency (inside build.prop or any other file) of checking, obtaining IP address, to optimize that, not to have huge battery drain because of WiFi environment?

General :: Battery Drain Much Faster Than It Was Before?

Jul 5, 2012

i've just flash a new miui rom on my o2x. and i found that the battery drain much faster than it was before. last night i had 14% of battery left on my phone, and this morning it shut down due to out of battery. so i pluged in my wall charger while my phone was off. and when it showed the green fully chargeed bar i disconnected the charger and boot my phone in to CWM recovery to wipe battery stats. then i reboot the phone into android and u know what? the phone show 100% of battery only in 3 secconds and then it show 1% left. i connect the charger and the phone show that it's being charged? how can it charge a fully charged battery? and the charging speed is faster as light. it's has been charging about 15 mins now and it show 46% charged. may be google was wrong saying that batterystats.bin does not affect the measurement of battery level.

General :: Battery Drain For No Apparent Reason

Jun 1, 2013

Just recently, my captivate battery has been draining very fast. I've been going from 100% to 0 in about 8-12 hours. The main battery consumer is Android System. There are no processes that are keeping the phone on according to BatterBatteryStats. I loose about 7-8 percent every hour while it is in idle/deep sleep. If I enable the extreme setting on Juice Defender, it bumps up the battery life to about 45+ hours. But if I use juice defender, sending and receiving mms is very difficult. I tried it on another spare battery and it gave me the same results. This problem started earlier this week and was present when I first flashed a ICS rom back in June and hasn't gone away yet. I did not change any settings or flash anything new to my phone. One day it suddenly went from 100% to 40% in 5 hours and after I rebooted it dropped to 5% in a matter of minutes. I recalibrated the battery but that did not do anything.

General :: App That Will Show Which Apps Drain Battery

Oct 2, 2011

I get pretty bad battery life. I wiped everything and reflashed the ROM and only installed about 10 apps instead of my usual 150 or so. Total difference in battery life! Except I want want my apps back, at least most of them.

I'm wondering if there's a way of finding out which ones take the most juice or are always running when I don't want them to do I can get rid of those few.

General :: Toggling WiFi On And Off Drain Battery?

Jun 3, 2013

Will toggling Wi-Fi on and off drain your battery? I'm asking this because I read:


Essentially, you want your Wi-Fi sleep policy to be "Never" because when the Wi-Fi sleep policy is "Always," your phone searches for Wi-Fi more often and that drains battery (I think that's what it is saying).

At the moment, I toggle the W-Fi on every time I'm using it and off as soon as I'm done using it in an attempt to save battery. I'm not sure if this actually works or it's actually draining my battery because it would search for Wi-Fi every time I toggle it on.

On my Samsung Galaxy S4, I can't find Wi-Fi sleep policy as mentioned in the article, but I found "Keep Wi-Fi on during sleep." Am I supposed to set this setting as "Always" to save battery life?

I toggle Air View and Smart Gestures on a frequent basis as well--not sure if I should do that too.

General :: Completely Random Battery Drain?

May 11, 2013

My Xperia Arc S has a really, really weird battery draining issue. The battery drains in 10 hours on standby. It seems completely random and happens as long as the battery is in the phone (even when it's off). I was rooted and had a custom rom and kernel but I've switched back to the stock firmware and guess what: the battery still drains randomly. I also bought a new battery with twice the capacity of the old one but nothing changed.

General :: MediaServer ICS 4.0.4 Massive Battery Drain Loop

Jun 12, 2012

I am a long-time lurker of XDA Forums and had an issue that I could not resolve on my own. I have upgraded my Xoom 4G to 4.0.4, stock, locked, not rooted. Factory reset recently and have tried everything to my knowledge to fix the following issue.The mediaserver is in a constant loop. There are no music files, pictures, anything on the device right now. Here are the few logs that have looped (I used OS monitor to find)

cpcap_audio_configure_power: regulator -> stanb
cpcap_audio_configure_power: regulator -> enable

It happens every few seconds and keeps the tablet awake constantly. The battery is in a huge drain.

General :: Battery Drain SGS2 GT-i9100 Android OS 98%

Jul 26, 2013

For the last 5 days I am experiencing extreme battery drainage(Android OS nearly 100% Battery Usage ). Back when it began I did not install anything suspicious or battery consuming software. I never go full screen brightness, and all unnecessary apps are either deleted or disabled. I have tried Factory Resetting, Wiping all possible caches, systems, internal/external SD cards. I even tried manually deleting all folders from my PC. I have tried installing custom kernels, roots and even stock ROM. Right now I'm with stock ROM with CF root.

Phone state: Model number- GT-i9100; Android 4.0.3; Baseband v. i9100XXLPS, Kernel v. 3.0.15-i9100XXLPQ-CL223505 se,infra@SEP-94 #3; Built number IML74K.XWLP7. And here is what I get from the battery report :


I have tried full discharge and charge to 100% and calibration. Even cleared the battery stats It just doesn't work. I am using Nova Launcher. Even after going back to TwLauncher I am still getting 98% Android OS usage. I don't use Data Mode and Wi-Fi isn't always on. When charged and calibrated at 100% at 21:00pm, in the morning at 9:00am phone battery is completely empty and shut down.

I'd like to use the stock ROM, with a nice battery stable kernel & still with Nova Launcher. NOTE: This is still happening with a NEW battery.

General :: Nexus 7 / Android 4.2.1 - Battery Drain On Sleep

Jan 11, 2013

I'm having problem with my Nexus 7. I have Android 4.2.1 on it. I've been using it for about a week now and every night i would turn it off, but in the last few nights, i decided to leave it on sleep mode to see how the battery life was.

On the google site, it says that the Nexus 7 should have 300 hours of standby. Is that the same as 300 hours of sleep? Because when I left my Nexus 7 on overnight, it drained from 55% to 33% in about 8 hours. That doesnt seem like 300 hours to me.

Also, I've tested it again, started at 100%, no wifi, no gps, no apps running in background, no syncing, in sleep mode, and it's draining at about 2% and hour. I've read on this forum that people have been getting like 2% every 8 hours on sleep, or even overnight. I've never used 4.1.1 so I dont have anything to compare it too. Does the 300 hour standby time mean powered off Nexus?
