General :: Xperia P Sudden Battery Drain
May 22, 2014
i have been using xperia P for more than a year and um quite happy with it except one fact which is the battery drain issue. my phone is running stock JB with nemesis 6.3 kernel and some other excellent mods.but when the battery level is below 40-30% it suddenly falls below 20% both with the stamina mode on and off! i have tried almost all the stock based custom roms and this issure persists.this doesn't happen when the battery level is above 40%, i have been facing this issue since i bought it!

What's the best way to determine why all of a sudden my battery is losing it's charge more quickly than normal? I checked battery usage in settings and everything seems reasonable. I can't think of a newly installed app that might be causing it. (HTC Rezound, ICS) ADR6425LVW

I upgraded the firmware on my X10 to R2BA020 (Rogers) last weekend, and have noticed that ever since, maintaining a 3G data connection seems to drain my battery much quicker than it used to under the same conditions. I tend to tether my X10 to my laptop using PdaNet at work. Whereas doing so under the old 014 stock firmware would result in my battery dropping from 95% to 55-60% over the coarse of my 9-5 workday, it now drops to 55% by noon. I have verified that my X10 is indeed charging over the USB connection to my laptop, and nothing other than the firmware has changed. So I'm not quite sure what the issue might be.

While using my Galaxy i9500 it crashes and phone automatically restarts with 0% battery percent
I tried this Battery Calibration app but it didn't work It says battery stats file doesn't exist!
I tried installing new rom but now as soon as I turn on the device it works for like 2 minutes in its real charging percent (e.g 60%) then crashes and restarts to 0%
The battery is original and It's not swollen.

A few days ago I updated to 2.1 . And the phone works great. Now the thing is that yesterday I noticed the battery was draining a little bit faster than usual, I had been using the Particle Storm Live Wallpaper, so I thought that was the reason. What was my surprise when I changed to an static wallpaper and noticed the battery kept going down really fast. I checked the battery usage and it said that Wifi was draining 33%, Screen 20 something and the live wallpaper only 3 %. Is it normal for Wifi to drain so much battery? Does it depend on the use or what? Shouldn't 3g drain more battery than Wifi?

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.

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.

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.

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?

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.

does sweep2wake drain battery? I think the screen is completely off while phone is sleeping and hence doesn't use any battery at all but to use sweep2wake the screen needs to be on all the time.

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.

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.

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

I was wondering, if I set wifi off but I keep the global sync option on in the 4.2.2 tiles, does the apps will try to sync even if wifi is off, and then drain a little bit off battery ?

my Samsung s2 on jelly bean 4.1.2 drains battery alot while even in off mode not only that, whenever I press the switch off key the phone won't give me various options of restart, flight mode , sound mode and the likes, the phone will just go into off mode directly.

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.

I've been here and XDA for quite a while but I recently started getting an increase of battery loss. Yes I know all about the not charging anymore once reaching 100% but that isn't the problem. I flashed Myns 2.2 R3 a while ago along with Kings #11 CFS. I was so happy when I realized it would take ~30 hours with occasional use and BeeJive running to hit 15% and warn me about low battery. It was only giving me ~23 hour with the same settings on Fresh 3.4.0.1. A few days ago, it started dropping rapidly and I'm not sure what caused but I was able to narrow it down to a few things. I remembered on that day, I dropped it once. I prayed to god it was okay. Picked it up and everything was working fine. I go and install a few updates and forget about it. Didn't notice the battery drop until the next day. I was only getting ~17 hours with everything kept the same way. Is there a log that I can access of everything I changed? I used Google nav for about 8 hours non-stop and while it was charging 2 nights ago, the battery never increased. That has never happened before, it would always charge more than it would drain. I didn't want to wipe and flash everything back since it's going to be a long week. Had a family gathering yesterday and gave my little cousins the phone to play with since it had so many games. There's another dinner tonight and wiping it would be out of the option now and until next week. Even then I think I'll be hesitant to do so since I don't even know if the problem lies within the apps.

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)
Code:
setup_dma
cpcap_audio_configure_power: regulator -> stanb
cpcap_audio_configure_power: regulator -> enable
[code]....
It happens every few seconds and keeps the tablet awake constantly. The battery is in a huge drain.
