*jump to ashtricks for immediate problems without reading software/ROM changes.
I know this is going to be made especially difficult with all the different software/combo's that can be loaded, but I have to post this up and see if any one else has seen this and if it might be hardware or software.
I have a HERMS 100 (8525). I first got the phone in April with WM5 (don't know which build they might have been on then) and which ever Radio was coming on them then. My battery would usually last 2 days with my avg use.
This has been the case threw upgrades until the last 2-3 months. I upgraded From one version of WM6 to VP3G's 2.X build of WM6 and I upgraded the radio to which ever version was the newest at that time (maybe 1.47 or 1.50). I Noticed a sudden drop in battery life, but the phone pretty much always made it a full day even with high use, so I didn't think much of it. I did notice about this time that sometimes the phone would alarm me and say it had 20% battery remaining, but if I rebooted the phone it would say 80 or 90% power remaining when it came back on and work fine the rest of the day.
The following has been over the last month. I upgraded to VP3G's 3.0 and again later to 3.6 and again to 3.62. I noticed the battery continued to degrade throughout this time. So I upgraded the radio to 1.54. The battery continued to go down hill at an even rate, but I noticed something else, the battery would not take very long to charge, but was dying faster and faster.
Well I started tracking and experimenting. Starting last week (no change in software or ROM's for the last 2 or 3 weeks) the battery would rarely make it through the day even when the phone was not in use any during the day (Granted I get no cell service at my desk at work, but I never have even back when the phone would last 2 days searching for signal). Most days last week it wouldn't make it 5 hours from being unplugged even when the phone wasn't in use. I decided to run the battery all the way down to where it wouldn't even turn the phone on anymore as I had heard sometimes you needed to do that after a rom upgrade. It did not help, but I noticed that the phone said the battery was fully charged within 2 hours from being completely dead.
*
Today was the worst, I unplugged it after being plugged in all night. Unplugged it at 6:45am. I did not use the phone, it just stayed in standby (I hadn't even taken it out of standby any today. I am at work with no service (When I say no service, I don't mean sometimes it finds something, I mean no cell service from any carrier makes it past 10 feet of the front doors entering the building and I am about 150 feet from the closest wall to the outside). I grab the phone at around 10:30am to check on a meeting notice, clicked on the phone to wake up and the battery alarm alerted and the battery said I only had 20% power remaining. In 5 minutes of doing what I was doing the battery had gone down to 10% remaining (so the phone went from lost 90% of it's power, never being used in less then 4 hours). I went back to my desk, plugged the phone back in and within an hour I noticed the amber light on the front that I relate it to telling me it's charging had turned green, I unplugged it and checked it and the battery said it was full 100%. Could the battery really charge that fast?
*
I know this would be easier if I could remember what radio and what version of WM5 came on this phone and loaded it back on and I am in the middle of downgrading the radio since I had ran WM6 with no battery issues separate from WM5 until I did that one upgrade with the radio. I guess I am curious if this could be a hardware (phone or battery) where it's not charging fully or if this seems to be a software issue.
I know all the factors that can be involved make this hard, but thanks for any responses you guys can give.
ok, how about this one, Is my battery screwed? I notice while I am using the phone the battery gets really hot. Today it did the same thing of all of a sudden saying I had 10% power after only using it for 5 mintues, rebooted the phone and now I am back to 70%.
Hi,
There's a lot on here about this problem. Have you read the wiki?
Some solutions you might try:
- turn wifi off.
- turn off all beams
- put in the fake server trick.
- search to see if you have any software that continuously polls the battery or is seeking an exchange server
- ensure all your apps fully close rather than minimise
- invest in a new battery.
WB
Thanks, I have gone through the wiki Continuasly since I got the phone in April, but with all the stuff out there, I could have easily missed something.
- turn wifi off - Never turn it on
- turn off all beams - Beaming disabled
- put in the fake server trick - Have to research that one
- search to see if you have any software that continuously polls the battery or is seeking an exchange server - have to check, don't have exchange server setup. I do have it checking emails every 15 minutes, but I never had any issues with that setting and the battery lasting a couple of days
- ensure all your apps fully close rather than minimise - X button set to close not minimize and I often check it to see whats running.
- invest in a new battery. - Will be doing that next. Just waiting to see what case I might get for Christmas.
Thanks again, I will research those other items.
I had a similar problem where the stock battery would only ever last for ~7-8 hours - even on standby. I got an extended life 3000mAh battery and that managed to last for about 14 hours.
I had a talk to HTC and they agreed to warranty claim it. I'm still waiting for it back... It was sent back to them on 14/11, and I'm still waiting.
Stop your device checking for emails for a few days and ses what happens. Definitely install the fake server trick. Activesync continuosly trying to do its dirty work can be a pain in the arsenal, at times.
Let us know how you get on.

Well I turned off email checks last night and disabled the radio this morning so it wouldn't search for signal when coming to work and set the phone on my desk. I never used it this morning, just had it sitting on my desk in standby, until about 4 hours after I took it off the charger and the phone buzzed me and when I checked the phone the battery said 0% remaining and the phone cut off a few seconds later (now I am sure if I would have turned it back on the battery would say something like 70%, but I didn't do that this time). I left the phone off and plugged it into the computer to charge, the LED on the front come on amber for about 20 minutes then went to green. I turned the phone on and it says 100%. I don't see how the battery went from 0 to 100 in a matter of 20 minutes.
I did a lot of searching the last couple of days and phone issues from email to bad manufactured batteries (which I happen to have the brand someone suggested as a bad one), I also saw people pointing out do the fake server trick, yet I can't find a single time where anyone said what the trick is or how to do it. Not even in the WIKI where the trick was mentioned as a possible fix (or google for that matter, just the same words first posted in a thread here about it).
So, how do you do this server trick?
I plan to get a new battery after Christmas at any rate.
Check this thread:
http://forum.xda-developers.com/showthread.php?t=338421&highlight=fake+server+trick
I was having the same battery drain problem (less than 8 hrs on a full charge), I did the fake server and turned off auto day light saving time checking the clock settings, I now get 12 - 15 hrs on a full charge.
I'm running vp3G's 3.62.3 AT&T ROM with radio 1.54.07.00
Thanks! I was just finishing flashing a new ROM when I saw this. I did the fake server trick, but this rom doesn't have the Dya Light Savings time option where the instructions say it should be. Maybe that's all removed by this rom. TIme will tell.
Thanks again.
@ Firehawkns
hey buddy!!
I am using a JasJam for the last 2 months. i dont know if my reply is useful to you or not. As far as battery life is concerned am impressed with mine. Am using TNT's latest ROM and my radio version is 1.54.07.00. I use my phone all day with couple of calls that last about 2-3 min each. But every night I get calls from my gf, to whom I talk for 3 hours straight(mostly starting from 11pm to 2 am) and every day I put my phone to charge after I finish the call. So after finishing the call I still have 50% of battery. Moreover our call starts right after I leave work at 11pm so by the time I reach home which is around 11.30pm my phone connects to wifi too. So all the time am on the call as well as an active wifi connection.
So as per my experience the battery life is cool. So try TNT ROM!!!
Interestingly enough, now I've got my phone back from the warranty claim, it's only drawing 81mA with backlight on, no wifi or BT. Before sending it back, it was drawing ~180mA with backlight on, no wifi or BT.
This will just about double the battery life that I get in theory...
Install BatteryStatus on your device and see what it tells you.
That is a cool program.
First off I really hope it isn't the phone, for one it's my third one from Cingular since the first two died within 2 weeks (back in may), second it's got one big gash down the corner where it came out of the holder and hit the road one day. I think that would be just enough reason for them to not do anything with it.
Anyway, I am going to replace the battery because I can't figure out why the phone is doing things like saying it has 20% batt remaing, then I reboot and it goes to 70%. I am hoping this is a battery issue. So far the phone has been unplugged for a tad less then one hour, has not been used and the battery meter is on 90%.
Battery Status is a kick butt program and I plan to do some searching today to see if people have benchmarked there ratings/draw. I notice mine jumps randomly. With wifi, BT, all programs all terminated, backlight on the lowest it will go and radio has one bar 3g sometimes, two bars Edge sometimes, but didn't change during watching this list below, but the MA does this every 5 second refresh:
111--190----125-----109----250----210-----140----135----226---111---etc.
I am currently running a barebones fresh flash WM6 rom with nothing installed except Cingulars media net/ISP settings, radio is 1.47.10. Going to try 1.50 today I think.
I turned the radio off just now and the MA went down (expected) to 84 and is jumping between that and 104. The battery has dropped to 80% since I listed 90 above. The phone has now been unplugged for right at an hour. Also it might be interesting to note that the little battery percent/bar icon on the "Battery Status" software once in a while will display -1% like it is right now, the phones battery display says 80% and when I tap the battery icon on battery status it jumps to 80%.
Anyway, I am just listing points since this thread is here, I know I need to replace the battery first before any additional insight can be brought forward.
Thanks everyone.
Hmm.. On my Schaps 4.22full, radio 1.54.00 on good reception (on Finnish network) I get around 30 mA with GSM and 3G when idling(no wifi, no bluetooth, no beam, backlight around halfway). With airplane mode on I get around 28 mA. Tried with backlight dimmest and the drain was 15mA on GSM network.
Usually I put the 3G off so the battery would last longer.
The phone takes more power when searching the network so it would be a good idea trying to switch the phone part off at your office.
Well, looks like it was indeed the battery. Over the last week the phone would randomly shut off (about 4 times a day), the battery would be at 10% within 4 hours even if the phone hadn't been used, and while using the phone you could almost watch the battery go from 90% to 30% within a 5 minute talk time, reboot the phone and it would be back at 80%.
Put in the new battery yesterday after charging over night and the phone not only didn't shut off at any point, but I had 60% power remaining by the end of the day (with some data and voice use).
The old battery was a Dynapack from China, that I had read on here is prone to defects.
Thanks for the help everyone, wish I would have gotten a new batt sooner.
How is the battery in your Optimus 7?
I don't have an exact estimate but I guess around 10 to 12 hours of normal use. With heavy usage like using Gmaps drive mode on and playing games I get a lot less battery time, though I still haven't made a true test.
My previous cell phone, Samsung SGH-T459 lasted me for days, it was truly a marvel but it wans't as pretty to look at as my LG E900. Though it had many more basic functions than my LG E900
Yeah sadly powerful phone != good battery life. Looks like you get basically the same as me. I bought 2 batteries and an external charger from Hong Kong for $15 though, so that should help.
My battery lasts for about a day and a half of normal use with UMTS and wifi on 100% of the time, with the odd game thrown in. I also have a Galaxy S2. The same use sees about 9 hours of battery life on it. I find the battery life of the E900 (with Mango beta) extraordinary for a smartphone and I'm very honestly thinking of selling my SGS2.
I see three types of scenario
normal day: no wifi, 6 hours of normal usage, plus 18 hours of laying in one place, and then it says "battery critical"
out of office day: 8 hours of moving in areas where are no GSM network in range (basements, garages, etc)
weekends: no wifi, laying in one place almost 2 days
My LG E-900 survives 2 business using the following settings:
- Regular 7392 software
- Connected to Deutsche Telekom (900 MHz)
- EDGE instead of UMTS
- No wifi
- No GPS
- Turning off data between 22:00 and 7:00 manually (i hate email notifications at night)
- E-Mail push for Active Sync account and 15 min pull for IMAP
- Daily Facebook sync
- Frequent reading of emails and writing about 5 mails per day on the phone as well
- About 30-45 min. phone calls per day (i have a fixed line in my office so it's not much)
Compared to my Samsung Galaxy S this is quit good, under the same conditions the Samsung asked for the charger during the 2nd day, the LG E900 has still about 25%-30% capacity at the end of day 2 (22:00).
As I use the LG E900 more and more my "old" HTC Legend is breaking standby records every week, about 7 days without charging. I don't use data or voice with it frequently, but it is connected to the UMTS network (O2 Germany offers GPRS and UMTS but EDGE only in very few areas). On my last cruise vacation the HTC Legend survived in standby connected to the GSM cell on the ship almost 10 days. Thus new cell phones still provide a good battery life in case you use them as regular phones, but who wants to do that?
5 days is my record
1 or 2 short calls/day, a few texts/day.
Location services off except when (rarely) needed.
Wifi off except when (rarely) needed.
Email sync on demand only (3-4 times/day).
Check trains/tubes twice/day.
Don't use it at all for music/radio.
This results in 3-5 days life.
I'm getting about 1.5 to 2 days normally - a mixture of texting, tweeting and internet, as well as the occasional call, switching between WiFi and 3G throughout the day. Obviously hitting up the GPS or internet radio kills it (about 4 hours of Tune In Radio take it to flat from a full charge), but I'd have to say I'm pretty happy with it, even after being used to a Nokia.
hi...i just bought an e900 and my battery life is terrible with latest rom.
like 6 hours and the battery was 40%. didnt do much on it!
The same problem. I'll try to reflash to Open Europe. Originally I have StarHub
my battery with:
3g active
gps active
data active and push in real time with facebook and gmail
i start my day at 8:30 and finish at 00:00 and beyond one o'clock my optimus tell me to charge.
mango update rtm
i live in italy and my operator is telecom italia mobile
I have no signal at home (from 19:00 to 00:00 and beyond)and when to look for signal consumes more energy from what we know
sorry for my bad english
Nothing Changed for now.
At 9am I disconnected phone.
At 7pm battery was critically low

Short battery time
I am having the same short battery issues you are describing and also the battery status indicator bug...
I made an experiment the other day. Fully discharged my phone and then recharged it to 100% at night. Turned data on (HSDPA 1900), wifi and location services were off, and activated battery saver mode. No app was open.
In the morning (7 hours after that) as soon as I woke up I checked the battery meter. It had 68% left!!! How could the phone lose 32% of its charge without doing anything but staying idle?
This is a way I found to charge and use your phone when your phone goes off due to low battery. This has been tested on the LG Optimus 7, HTC 7 Trophy, Samsung Focus and HTC HD7 so this may work on other devices. (Unknown about the Samsung Taylor or LG Panther)
1. Make sure your phone is off due to low battery and can still switch on
2. Turn on your device on.
3. Wait 5 seconds after you see your OEM logo (e.g. SAMSUNG, LG, HTC), then plug in your charger. (If your device turns off before 5 seconds or cannot switch on at all, this will not work for you.)
4. You would see your OEM logo for a few seconds and your network provider logo (depends whether your device is OPEN or using a Carrier ROM) then you would see the animated Windows Phone logo and your SIM PIN or Wallpaper.
Troubleshooting:
If you feel a slight vibration or hear the "low battery" alert and the device goes off after the animated Windows Phone logo, you have either waited too long, charger is faulty or not turned on or your Windows Phone does not support this.
If your device turns off before 5 seconds or cannot switch on at all, this will not work for you because your battery is completely dead. Charge it properly for 8 hours.
Thanks,
AlivePhilemon
(NOTE: This works only for versions 7.0.7004, 7.0.7008, 7.0.7355, 7.0.7390 (NoDo), 7.0.7392, 7.0.7661 mojo, 7.0.7712 mojo, 7.0.7713, 7.0.7714 and 7.10.7720.68 (Mango) flawlessly. It does NOT work on 7003. DO NOT do this on 7003 as there seems to be a bug in the device firmware which MAY render the device unusable. 7003 users use this AT YOUR OWN RISK. I will not be responsible for any damage caused to your device when this trick is done)

Have you unbranded your phone? Did you force the Mango update? If you did so, you might be missing the LG firmware update that's supposed to give longer battery life.
I had the same short battery life issue, and it went away after I rebranded my phone and got the 1.0.9.10 firmware for my e900h.
If I use only for calls, sms and mail (with wifi on all the time) probably 2 days, but if I play games,music, videos etc. only half day. If only there was a better battery available.

I haven't unbranded my phone, as it still displays Vodafone as the carrier and I got all the updates keeping it branded. I forced the mango update because my country only got marketplace support after that update (I live in Colombia) and I wanted to have a fully functioning phone and not have to wait a month or more for that. I did get a couple of LG updates, one after NoDo (If I remember well) and the tethering update too.
You suggest that those that forced the mango updated missed an LG update, are you sure about it, or just giving your thoughts? For what I've read I haven't found a pattern yet, as I'm not the only one with the feeling that battery is not lasting enough. Also, i think the 1.0.9.10 FW is for E900h only, I have only seen that FW in the posts related with phones from Canada.

I'm sure of it for the e900h and I see no reason as to why this wouldn't apply to the e900.
I had abysmal battery life after forcing the Mango update, my phone could barely last a day.
Now, that I received the missing LG update that a forced Mango update skips, my battery life is much improved. While 1.0.9.10 is e900h specific, I am sure that you can check to see what firmware version others with the e900 have to see if you are missing a driver update.

Same here.
Battery life on my LG Optimus 7....
Mine's like only 10-22 hours... But it should be more like 50h+ atleast when it's in standby mode but it isnt.
The question will be if it is worth to buy a new battery to check if it can last longer?
How is the battery life compared to previous state? Better, worse or about the same? Please vote
It will be the same for the first 3 days and then gets better by a whole one more day (Don't know why).
For me the counter at the 1st 3 days said it will last for 1 day and 18 hours now it says that it will last for more tan 2 days and 18 hours and some times 3 days and 5 hours.
I tested it and it lasted for 2 days and 11 hours and there was still 17% of battery life (Lite usage , some 3g usage and listening for 30 minutes for music and around 2 to 3 calls of 15 minutes total).
Hope that helps
It does, thanks! Replies are welcome and there's a poll on top so please vote
I leave WiFi and data connection switched on all te time ... I used to get about 18 hours ... Still get Te same ... Comparing 7720 RTM with official mango update ...
Sent from my SGH-i917 using XDA Windows Phone 7 App
Battery life on my focus with mango and even before mango has been better than any other smartphone ive owned. I cant complain at all.
I was going to post a message on the battery too.
Poll is a great idea.
I just finished charging it after installing Mango. I will see how much it lasts.
I wanted it to drain out and recharge it so I can see how it is with Mango. It didn't gave up easily.
My initial impression is that battery is improved.
However, when talking about battery life, it's crucial to keep in mind what services the phone is using and what apps are installed.
For example, things like sound enabled for key presses, or having WiFi on or off, whether you play games, what apps you run, etc are important.
For my test, I want to see how long the battery lasts with a very basic usage. WiFi turned off, without running too much app or play games, giving\receiving few calls(I do not talk too much on the phone).
I heard for example that Samsung app Now drains out battery pretty fast.
Also, lack of signal in some areas, also means alot for power consumption.
6 days + 7 hours
Usage:
no WiFI enabled
no games played
max 2 hours of talks in total(I talked once like 1 hour)
How does it sound to you?
For me it looks fine although I am wondering how much would it last if I have Wifi enabled(for the same amount of talking duration).
6 days, What?
I only get 3 days and 15 hours if not using the mobile phone at all.
Can you please post a screen shot of the battery saver
I am in the 7th day actually now
The statistics displayed in battery saver are very wrong. I am not sure how it computes the remaining time.
When I posted yesterday, it showed 6 days since charging and only few hours remaining.
Now it says, 7 days and 1 hour since charging, remaining: "less then 1 hour", remaining battery life: 6%.
Last time I charged, I noticed that battery doesn't get to 0%, most probably it needs some energy to preserve data, so it will probably only keep me for few hours today.
I will post a photo soon, right now I don't have other device to take a photo of it.
Last time I fully charged the phone was when it was completely empty. Maybe it's important.
I can only hope the battery life won't degrade in the next year.
Ok, so now we have some votes so I can share my bits and why I started this thread.
Before 7720 I was on 7660 (Mango Beta1, not 7712)
The battery was certainly better than in NoDo. Actually, I'd say my phone had the best battery lifespan in 7660, than in all other versions.
7660:
Standby: 3+ days.
Night stand-by: 3% consumed (cca 7-8h)
On average use: 1 day and 20h
For me, average use means:
- Cellular data connection on during the day (I switch it off during the night)
- Some wi-fi to check new apps, say 20 mins daily
- About 1-2h playing.
- Minimal calling (several minutes).
7720:
Standby: almost 3 days
Night stand-by: 4%
On average use: 1 day and 10h
Stand-by means no data connections.
As an observation, stand-by time is almost similar. There is a noticeable drop in battery time once data connections come in play (cca 10-20% for me, compared to 7660). I am not going to revert to 7660 to re-test.
One more thing: after upgrading to Mango, I had AccuWeather app installed and running in background. I had to disable it because the battery life was getting under 24h (actually more like 20h). So if you have apps that run in the background, that might be one of the reasons why the battery life dropped for you. Once I disabled it from working on the background, I'm experiencing very similar times to 7660, but still the data connections consume just a bit more.
How are people getting 3+ days!? When at 100%, my Focus usually says like 12-13 hours. I have a Gmail email account set to push, and a Hotmail account set to receive email every hour. I have Facebook, Twitter and LinkedIn linked on my phone. I have Messenger and Facebook Chat set to off. I always have wifi/bluetooth off, unless I need it for a few minutes.
I am thinking I should flash to 7004 again and update to Mango from the beginning.
I walshed my phone for Nodo, then did the fix, then used the windowsphonehacker method for Mango and got the "Samsung Update" when Mango was released.
Thinking maybe my install is just a little off due to the route I took to get here.
Anyone else have battery life as bad as I do? If I use my phone non-stop for like an hour (people hub, web browsing, facebook app, etc...) I can burn through a ton of battery.

Make sure to do a reset immediately after the update to the *official* Mango (not the tricked one).
The BL seems to be much better and is a small cost for the rewards. You will erase your phone, but it's worth it. The BL seems to be much better than NoDo.
To increase battery life when you have data connections on:
- keep the brightness to low
- keep the ringer on vibrate when you can
- disable background apps
- don't keep applications opened in the background
These save me a good % of battery on a daily basis.
Also, unless really necessary, disable data connections during the night.
@rkremers: with the above settings and no data connection I get 3-4% loss evey 8h or so. If you calculate, that's about 12% per day. Which gives about 9 days for standby, as someone else on the forum was saying, which I incline to believe. This weekend I will test this too. I won't touch the phone at all until Sunday evening. So I'll have the power consumption on standby for 2 days.
dang enderpsp... Now I'm for sure gonna flash to 7004 and start from scratch, to see if it gets better. Probably do it Sunday sometime due to busy Friday night/Saturday.
Thanks for weighing in...

You're welcome. Keep in mind that a "tired" battery can also be responsible. I see lots of wrong advice given across the forum.
How to Prolong Lithium-based Batteries is a long read, but in the long run, you'll benefit from it, as a lot of devices use nowadays these types of batteries, including cars!
LE: As a refresher for me, I searched again and found this. While it's not as detailed as the one above, it contains good advice.
so, I flashed to 7004, then let Zune upgrade to Mango... I'm at 95% battery now, and it says 1 day 5 hours... 1 day 10 hours with battery saver on.
Not sure if it will actually last that long, but before I did this, it would say about 13 hours on a full charge with battery saver on... so clearly my phone did not like being walshed, unwalshed, hacked to mango, etc... Guess in the future I'll install leaked versions of WP7, but go back to zero when they officially release.
I finished the weekend standby test (2 days). This battery is 9 months old.
Setup:
- Battery saver off
- No data connections/wifi
- Sound on
- Low brightness
- No alarms
- No background apps
- No touching the phone
After 24h: 91%
After 48h: 79%
Had a phone call (didn't answer) and one alert (didn't dismiss), in the second day. After 24h I just turned on to check battery status (<20s).
The end result speaks for itself, approx 10% battery per day. So, it can give 9+ days on standby.
Next weekend I'll do the same test with battery saver on and update here.
I just got a Samsung Focus and the battery seems to lose power at the rate of 2% an hour. Is this normal? data connection is not active, no games, no youtube videos just a quick e-mail check and 2-3 min call.
Is this likely to improve after a few more battery charge cycles? I have followed all instructions like disabling location services and background apps.

How is the antenna signal? What type of connection?
Antenna signal is pretty good 4-5 bars. Just regular connection not 3g. E-mail auto syncs have been set to manual.
Battery seems to be original Samsung.
I have an LGE Nexus 4 and I just got the 4.4 update a few days ago. I love the update so far, but one thing that really irritates me is:
Battery life! Ever since updating to 4.4, Exchange services is using up more battery than my screen! Other power hungry apps since the update are: Mediaserver, and Android System. (I'm running Nova Launche Prime, that's probably responsible for the android system usage.
I used to come home from school at 5PM with around 35-40% Battery. It's currently 12:45PM and i'm already at 65% :S. Anybody with tops and tricks to help me conserve battery life please do share with my self and the community!
thanks world ( ::cyclops:

I don't think you've provided enough information for us to really tell you. Try getting BetterBatteryStats and then check for yourself what's going on. Sven has fixed it to work on 4.4.
I've experienced the battery to be affected negatively on 4.4 as-well.
For now i turned off the voice command [ok google] which seem to help a bit but still not as good as 4.3.
ITs location services... turn it off and see how much better battery life you get or use device only then check your google services useage
Exchange Push is the issue
I have found that changing my Exchange settings from "Push" to check every X minutes has greatly improved my battery life. It seems to be much more inline with what I was used to with 4.3.
Hope this helps,

Well... I flashed 4.4.2 the other day and I saw my battery plummeting like mad... so naturally the first place I came to was XDA, and saw that a lot of people were having a big problem with battery life.
So I didn't do any battery pulls or anything like that on my N7100, but when the battery went from 85% down to 12% what I did was to turn on everything that I could in order to drain the battery... turned on Data, WiFi, turned off the battery saver etc. etc.
Down at about 6%, I got that alarm with the notification to plug in the charger but I just let it go.
After a while, the phone wouldn't turn on at all... nothing. Nada.
So I plugged in the charger and let it go.
I checked it in about 1.5 hours and it said 100% but the red charging LED was still on so I let it charge for about another half hour and finally the LED turned green.
I turned on the phone and held the power button until the screen flashed three times (About 15 seconds), and let it boot up.
I had 100% charge last nite @ 11:39, and right now on standby (12:45 the next day) I still have 95% on the battery.
Strangely enough, I didn't get one call on this phone all day... but when I don't answer my Note 2, people just try the other number on my iPhone 5s.
Granted, I never leave the WiFi on or data... but I have the stock ROM with all the crapware that it has... but I flashed that French version of KitKat off of that site that I won't mention (But it's that one that if you're not a paying member, it takes you half a day to download anything).
Pretty happy with KitKat stock rom so far, but that first few hours when when I saw my battery sucked dry before my eyes was pretty disconcerting.
Hello all
First post on this forum, hope I'll do ok
I've just got my Axon 7 last Thursday. I had before a One+One and I was pretty happy with it, but I'm a geek so when I saw the Axon, well...
So on Thursday, when I first started the Axon and got the message "Do you want to reinstall your apps"? I said Yes and all the Apps I had on the OnePlus got installed on the Axon right away. Mistake?
During that first installation, the battery of the Axon went down like crazy. From a 100% (I had slow charged it the night before), it went to 5% in 3 or 4 hours. Got quite hot too. So I figured: "lots of work, let's see later" I charged it with the charger right after, fully.
The next day was fine. But I'm not a player, my main uses are the social apps (Facebook, Twitter), some text messages, one phone call that lasted 15 mins, web browsing, and some pictures (like 10) at night without flash. Got home last night with 10% left. Figured it was ok. So I charged it fully again.
This morning, waking up, the battery is at 80%. I haven't touched the phone... GSam says that Mobile Radio used 48% and the screen 34%. I activated the WiFi when I woke up and GSam says 18%.
I didn't have that "issue" with my OnePlus so...
My mobile network uses 4G but with my OnePlus, inside my home, I would only have something like H+ or rarely 3G.Maybe the mobile network is draining the battery. Since I haven't rooted the Axon (is it possible? I'm not too found of that), I can't used apps like WakeLock to see if something else is draining the battery...
I have installed of course the latest update from ZTE.
What do you think? Should I do a factory reset and restart from scratch, not reinstalling automatically the apps? Those are pretty basic apps btw, like I said no games, nothing fancy...
Or... do I have a faulty battery?
I chose this phone over the OnePlusThree because of its battery, I would be quite pissed if I had the only Axon with a defective battery
Thanx for your help and comments
If you have a 4g service and your phone's can't connect to it then I'd suggest switching the data service preference to 3g or better yet, keep connected to wifi. This is just to establish if the constant network search for LTE is what's eating up your battery. I believe the first instance of getting only 3 to 4 hours can be attributed to the install of apps. GSAM indicators are approximate if you aren't rooted but it's still good enough to tell you what is eating up your battery.
Maybe a clean start can at least help you test and conclude if the battery is actually at fault.
Btw, FB app is the worst offender as far as battery life goes. I hope your problem can be identified and fixed soon
