Battery life

This phone is only lasting me about 8 hours before my battery will die. What can I do to help out my battery?
Sent from my SPH-D710 using XDA App

download an app call battery calibration, then after a full night of charging, go to that app and calibrate with the charger plug still in, after its done reboot phone and take it off the charger. drain the battery until it shuts off by itself. charge it back up while its off. then continue to use as normal. wait a couple days to see if the battery gets any better. my phone doesnt last too long either, im thinking of replacing the battery to see if thats the problem

Try removing some apps, that worked for me there was some apps that were sucking up my battery.

slap on a extended battery!

Kiss it three times, say two Hail Mary's and toss it over your left shoulder.
No seriously, battery life is very dependent on many things, and your statement doesn't come close to providing enough information for anyone to give you any real help. At minimum you need to provide the following during your 8 hours ...
- Total Display on time
- Brightness setting
- What you have auto syncing and how often
- Average signal strength
- Usage pattern (web browsing, calls, streaming video, etc.)
- Widgets on your home screens
- Screenshots of your battery usage and graph

My phone will also last around 8 hours if im constantly using it.

Thanks everyone for the responses. I will try out all the advice.

With moderate use, I get about 20 hours. With heavy use I get about 10-12. It's still enough to get me through the day
Love this phone!

[Q] Sleep of Death with Stock

So I read about other people having this problem with custom ROMs or rooted phones but I am on unrooted stock after OTA. I thought was one of the 60 or whatever apps I bought during the 10 cent promotion but I uninstalled them all and I still had the problem. It's not frequent but it's happened 3 times in the last couple of weeks. It's mildly annoying to have to pull the battery but the part that I can't live with is that whenever it this happens, my battery drains like crazy. The battery usage drops off a cliff and I caught this one after no more than 5 minutes. Any thoughts on this? I don't have an SD card so it's not that. Thanks!

to find the rogue app use betterbatterystats and cpu spy. not sure if they superuser. also badass battery works too.

Mine did this the other night on Calk's ROM. Something got stuck keeping the phone awake causing that cliff like drop off.

Happened to me on stock once, installed some game but didn't play it so I don't think that was the reason. It was either the default browser or the contact list.

Thanks for the replies. I figured it was an app but wanted to be sure before I started deleting things. I was just worried that this might be something to do with hardware or something.

I have same problem with different roms and i don't know what to do...

I had the same problem I figured out it was my wifi being turned on all the time. I have always heard leaving your wifi on when it's availible was supposed to save battery but I checked in better battery stats and saw there was almost 7000 wakelocks in a 5 hour period. I turned wifi off problem solved I only turn it on when I need to.

It is happend even wifi is off.

Your battery might be going bad... take it out and spin it on a flat surface if it spins freely the battery is most likely done.

My battery have 3 months old. My s2 is new....

Same thing is happening to my friend's white E4GT, I think there might be a defective/bad batch.

Major Battery Drain Help!! (100% -> 0% in < 5 hrs)

Firstly, I am fully stock in every way. I have been getting abysmal battery life from my phone.

Obviously I'm aware that the culprit is lookout.. i do like the services offered by lookout and would like to keep them. Disabling lookout does fix the problem but I'm wanting to hear potential causes and/or fixes..
Thanks for your time.

Which of the features does it offer you "like". Many times there are other alternatives for those "features" without the drain.

Im using lookout with no major battery drain. Looks like your wifi was on all the time. Low wifi signal may cause for wifi radio to broadcast with higher power. Smart stay will trigger camera every few seconds. Personally I use "Screebl" from play store - it keeps screen on by checking if phone is not laying flat. Install "better battery status" (need root for that) and it will allow you to see which app or service keep phone awake. Turn on power saving mode. In settings turn off wifi while sleep mode.

Try one power guard https://play.google.com/store/apps/details?id=com.onexuan.battery. and or Snapdragon battery guru. https://play.google.com/store/apps/details?id=com.xiam.snapdragon.app...... also I deleted lookout since i also had crazy batter drain I went from 100% to 88% in 45 minutes.

Thanks to those who replied. . However none of the answers have helped. .
Like I said, I am hoping to keep lookout as an unrooted stock user .. for now.
What isn't adding up is the fact that most users are reporting no issues with lookout draining battery..
So why am I having problems ??
As for weak wifi, that's not an issue.
Other ideas ??

I had the exact same issue. The only way for me to stop that was to uninstall it unfortunately

Don't use lookout.

Tried factory reset?

Be done with lookout
NOTE 3

Lookout Isn't doing that for me maybe a update is needed?
Sent Via Tmobile note 3

I keep finding Play Music running on its own and eating battery quite often. Maybe that's the culprit? Was happening lately on my Note 2 as well.

I had this issue just after using Root de la Vega. My battery was going completely dead after about 4 hours with light use and the phone was getting really warm like the CPU was pegged the whole time. I did a factory reset and have all the same apps installed and my phone now makes it easily through a 10 hour workday and 45 minute commute with heavy use (5h screen time). Try that if you haven't.

** Community Battery Life Tips & Tricks **

While we have VOOC and (some of us) a spare battery lying around, we could all use more battery life when we're away from a wall outlet. So..
Post your battery stats/power consumption details along with any steps you took to achieve it.

Enjoy all.

Here's my battery results after a full day's use.
Stock Oppo Color OS
Stock Kernel
Google Now OFF
Low Manual Brightness
Bluetooth On
GPS On
Keylights Always OFF
Vibrate on Touch OFF
Greenify: NONE
Snapdragon Battery Guru: LEARNING
[There is a very small part where the battery charged while attached to a computer due to syncing over a few songs. I only seem to recall that battery going up by 1% at this time]
Anyone have any suggestions?

After installing snapdragon battery Guru i mentioned verry low speaker audio during phone Calls. uninstalling fixed the behavior.
anyone else.

That was with about 3 hours of gps on and using Google maps and a route planner for my deliveries today. I don't know if that's good as I've yet to use it like this before.
I have all off screen and on screen gestures turned off except the 3 fingers for screen shot. Auto brightness and wifi was off today as well.
The other day I let my phone idle for 9ish hours while I slept and I lost 4%, that was also putting the cell data to edge though.
I also use the greenify app, not the built in greenify. Haven't messed with the built in greenify does it work the same way?
Tapped out on my beastly OPPO Find 7a

This has got to be a bug...
Unplugged, drove to work and noticed no drain on the monitor.
The phone was trickle charged by my router though overnight, not through the OEM charger

I disabled the gestures, that helped a lot.

I think its just a bug, mine seems to stay on 100% for a long time too. It does drop eventually. The battery life is very good on this phone though. I've never had it run out during a day yet. It does seem to better reflect battery use at it gets lower.

Yes you are right after 90 minutes it's dropped to 99 and 98, I thought I have to restart to get correct reading but didn't
Sent from my SM-A705FN using Tapatalk

I have same issue. Stays at 100% after 30mins or more of usage. As soon at it drops to 98% battery drain becomes normal.
I did the calibration reset code *#0228# and it didn't change a thing.
Battery life is good on this phone but nothing impressive.

Probably needs a few charge cycles for the battery to calibrate properly, happened to me too.

Still going strong, no power saving , 4g all the time , Bluetooth all the time, alot of games, Facebook and YouTube

My battery life

this phone is excellent on battery life.
when i first used it and charged it to 100%, I noticed the same thing, and was confused, checked to see if the phone froze, etc. But then I started to feel invincible from the overabundance of power. LOL.
