[Q] Terrible battery no matter what... anyone else?

I've had 3 or 4 different evo's and it's been almost impossible to receive decent battery life on almost any rom. It started with CM6 and I switched even though I loved it and went to Baked Snack or some other rom that stated battery life, but it just always ends up dropping on me no matter what. I thought my expectations were too high, I just recently got my last replacement and it's now 3-4 days old. I heard how CM7 and Miui's latest had excellent battery life so I couldn't wait to test them. I first tried CM7 and as long as it's on stand by or not being used the battery was pretty decent I guess. That's with Green Power free running btw. when I turn the phone on to start using it, the percentages just drop. Tried Miui after hearing how good the new battery life is and almost the same thing.
So, that led me to believe it was due to some program, but for the most part I keep these stock. One of the first things I setup are a Gmail account, FB account setup... then of course my apps are added automatically hardly any widgets ever run. If anything it's Buzzbox, I've got beautiful widget's clock now. I use Vlingo, not sure if it's a hog. When I check the battery stats, there's nothing crazy or out of the ordinary. Anyways... there's got to be something wrong, I'm guessing. I've got a regular battery and an extended battery and they both do terrible. I'm going to install a rom from scractch with nothing loaded at all and test the battery. I hate to do that, because testing will take awhile especially with adding one program/widget at a time to monitor the percentages lost.
Here's a list of apps I normally have on my evo and run occassionally:
Vlingo
Green Power Free
Juice Defender (before green power and GB)
handcent
buzzbox
facebook
Swype
Google Services
Voicemail
Are any of these battery abusers without me knowing it?
I normally keep wifi on and connect to it over the 3g data, although I believe Green Power said it cant control the data on the GB roms as of now.
Today, I started with 98% with my extended battery, CM7 and now at 1:00PM I'm at 70% Minimal usage.
Sorry for the long post.
Bluetooth is off most time and Wifi like I mentioned usually is on, because I heard it uses less power than mobile.
sorry for the long post.
Just looking for some assistance.

Restore it to stock.
Calibrate your battery.
Use it for a few days without installing all your apps. If the battery still sucks, then you are probably going places that do not have signal and the phone is searching a lot. Check About - Battery for time without signal.

get a seidio 3500 mah battery and you will enjoy your phone with every little feature turned up to the max

It is a Seidio
Of course it's not as bad as the original, but watching the batter go down 10% while I'm using it is very disheartening. Awhile back, I was able to get decent battery life, but I can't remember what rom, it might have been Baked Snack like 1.6 lol, guessing anyway.

Nuggyunlimited looks like he is onto something. I do not know if he has 4G or not?
I have had my best luck with mikFroyo.
What is going on with google maps? I have the same problem wiht MikFroyo

I am one of the heaviest users around, I stream pandora for about 8 hours , listen to music app about 2 to 3, check facebook and certain websites constantly, my two email acounts check every five minutes, my brightness is at 100 percent, my gps and location services are on, I'm overclocked...using 4.3 mikfroyo with sbc number 7...at the moment I'm using miui with sbc 7 for aosp roms, depends what you do, but either way no matter what kernal or rom you use I'll tell you, this battery will last you all day, this battery changed my evo experience...
edit: I don't use setcpu for profiles, just for overclocking, i dont use juice defender, the useless task killer or anything
edit 2: Conductive i had the same problem update to 4.4 or 4.3

so let me get this straight, average use is 8 hours of pandora, 8 hours of sleep, and that leaves 8 hours for facebook and etc, so lets say 4 hours total for a guesstimate, leaving 4 hours of non activity of the phone being off. 20/24 hours is "average use". I mean this is not a competition of who uses theyre phone more, all im saying is that with this battery you can do pretty much whatever you want without caring with ANY rom or ANY kernal you want.

No I use my bluetooth headphones for music from around 8am-6pm entire time I leave the house to the time I get home. Both facebook accounts every 15 minutes same with both.twitter accounts on xda off and on all day I.text a lot and use g talk a lot with a few calls I wasnt posting it as a battle I was actually just saying we get about the same times but I use the phone a little more and I was agreeing with you that the battery works wonders

i just got my evo after a hero.
the battery life is exactly what i expected. ive got a stock sense, rooted with clockwork.
i dont use widgets, no auto syncs. i have complete control over my device and it never leaves my hand. that being typed, i can get about 13 hours of up time.
yes, id like the battery to last longer but im not willing to have a fatty evo for the 3500mAh battery. I purchased a second stock battery, official HTC, so if Im gonna have a long day, ill have a battery with me.

Ok, yesterday I loaded Miui with nothing additional except changing the LCD density to 200, green power (which is useless since wifi doesn't work with this kernel) and right now I'm at 14h, 49m since unplugged with 17% left (normal battery). That's with minimal to average use. I notice when I'm using it, I can watch the percentages just drop, so I guess it's functioning normally and it's due to just my usage and programs, I'm probably expecting too much from my battery, once again I guess. I'm going to try your rom next with my extended battery.

I know what stock battery users go through, and with heavy use they don’t last too long, but I’m now in a different, horrible place entirely and I have the 3500 mAh battery!
I know that something is clearly wrong with my Evo but no one seems to know what it is. As I said I’m also using a 3500 mAh battery, but not to any advantage. In fact I get considerably less usage with this now then I used to get with the stock 1500mAh battery, regardless of the ROM or kernel.
Current specs:
HTC EVO 4G, Hardware 0003
16GB Wintec Class10 MicroSD
SEIDIO 3500mAH Battery/Camera Protector
Calkulin's EViO 2 v1.7.7 (have run several different Sense and CM ROMs)
HTC kernel #15v7 (doesn’t matter, have tried stock and every TM, regular and SBC)
Quadrant ≈ 1365
Linpack ≈ 33.05 MFLOP
and…(drum-roll please)
Battery Life: 70% after 6 hours, literally next to no usage.
Before middle of last November, if I charged the phone fully (without the benefits of SBC), and then just unplugged it on a Saturday night and let it sit unused for like 19-hours, the charge would be around 89%, +/- 1%, with the stock battery. In that same scenario now the 3500 mAh battery would have shut the phone down long before 19-hours rolled around.
Yesterday, using the 3500 mAh extended battery, no phone calls, Bluetooth on for about 20-miutes this morning for the drive to work and was turned off upon my arrival, and I’ve sent and received 4-5 messages on GTalk. That’s it.
The current status:
Charge: 70%
5h 52min unplugged
Up time: 6:15
Awake time: 1:20
Battery Usage screen:
Cell Standby: 42%
Phone Idle: 43%
Android System: 8%
Bluetooth: 4%
Display: 3%
Phone runs great; everything works great, no other issues. It once fell about 10”-12” onto plush carpet (kitten attack). It was in the Sprint case with the stock battery then, and has not been dropped otherwise. If anything, I am ridiculously careful with it.
Something happened the middle of last November like a switch was flipped, and battery life has been horrible ever since. Since we got our Evos back in the very beginning of June, 2010, I don’t think that returning it to the Sprint Store was an option then or now.
No one seems to have seen anything like this or have any clue what the issue might be, but it was suggested that I RRU it back to original, update it to current and then test the battery usage. Then, basically just live with it and see if it helped. After that, I’ll re-root and get on with life, whether battery life is better or not.
Any constructive thoughts are welcome. Thank you for your time.
Note: my apologies is this constitues a thread hijacking; not my intention, just saw title of the thread and it sounds like my life.

Thank you for the input. I thought about that so I tried the 3500 mAh in my wife's stock Evo and it runs forever. I'm so envious! I've swapped her stock battery and mine and they both run the same in either phone.
In mine, the stock battery usage is proportional, too. Fully charged and unplugged at 6:00 AM and with absolutely zero usage, sleeping screen off the entire time, by around 2:00 PM the stock battery was at 41%. That was also with very minimal synching (I've tweaked those settings nicely), no bluetooth, etc. I believe that the awake time was like 36mins. Sick, but unfortunately not in a good way.
Since it can't hurt, I think that I may do the RUU thing this weekend and then re-root afterwards. It may not help, but its literally the only thing that I can think of that I haven't tried.
Again, thanks for your thoughts. Have a great day!

Sorry, I've bypassed your rom for so long, but I've got it loaded now. Looking forward to trying it out. I can't lie I love and miss CM7 and Miui, but if my battery seems to last longer with a sense rom, then I'll be switching. So far it is very snappy and quick. Do you recommend I stick with the stock kernel or switch to something else? Do you use any setcpu, juice defender, green power or anything?
Do you have theme's as well?
Updating a titanium backup for my apps now.
I'll post back how it goes. I would say I had the same problem as the user above, but this has happened on mutliple phones and roms.
I know with a new phone you need to cycle the battery quite a few times. Someone told me roms were similar, even though I never understood why. Would you say that's true? In order to give the rom time to adjust to the battery and settings you need to give it 3-5 days?

what is the Best extended battery so far , that gives me more hours ?

Hello all ,
sorry if it's duplicated question , but it's very urgent for me
I've made this topic before :
[Q] When it comes to heavy Continuous using .. which rom / Ker gives me more hours ?!
and as you can see , i tried almost everything to get more " screen on time "
someone told me to get extended battery
so , could anyone tell me please that is the best one so far ?
and how many extra hours i will get with this one ?
i mean in heavy using
thanx a lot ,
and sorry again

Either get the 2000mah samsung extended battery if you want to keep the slim profile, or get one of the brick sized extended batteries from ebay

any reports about this original Samsung one ?
is it better or the other ones ?
i don't care about size
cuz i have a Case-Mate tough and SPG neo hybrid and i guess they could handle it , right ?
so , any help about exact tested ones ?

Search. The. Fracking. Forum.

^ tried ..
but found many topics with tens of pages

so far i think the original extended battery feed me well

The best kernel is void.echo, excellent performance and battery.
I've got the Samsung 2000mAh battery and you get another cover with it as its slightly bigger. Got me 5 days with void.echo. WiFi on almost all the time. Hes a picture:

They're also bigger ones on eBay but theyre fat and ugly. They are 3500mAh. Never tried them, never will. Ruins the look of the phone. Heres a pic from eBay:
I would go for Samsung's 2000mAh. My ROM is WajkIUI with void.echo. I hate siyah, it drained my battery in 5 hours, i didnt even do anything!

thanx a lot
could you please post some screens about usage ?
specially screen on time
i got max 3 ~ 4 hours with my current stock one
what about yours ?

u could also get an external 1350 mah battery from samsung
there is a link of it somewhere here
and also one more think u can do
disable one core
lock it at 500 mhz full load
undervolt it
and do the same to the gpu

Really? 5 days? I would love to see some proof of that.
there's no rom\kernel combo wich give you that long juice time unless you turn your phone on, put it in "flight mode" and use it as a paper weight.
Anyways i manage to get about 30-40 hours of medium + usage with Anker 1900mAH battery.

It's actually very easy reaching 5 days with wifi always on and GSM... If in all the five days you turn the screen on like 1 hour total.
Those statements of "my phone lasted x hours" without any aditional info are completely useless.

true, gsm only saves looooooooots of battery but dont get mad if you wont receive some of the calls. im happy with phone lasting about 30-40 hours with avarage use, wifi always on brightness set to 0 unless going outside- auto , and pretty much it. better than my desire anyway

Regarding those chinese batterys off ebay.. I dont have any first hand experience with them.. I ordered a 3000mAh battery for my Samsung Galaxy S (the first one). It took maybe 2-3 weeks to arrive, and by that time I had already upgraded to a Samsung Galaxy S II. I sold the Galaxy S to a friend, gave her the huge battery when it arrived.. she later said that the bigger battery didnt last any longer than the official original Samsung battery! She also had a couple of other chinese batterys that fit the standard casing, and she said those ones didnt last as long. I personally didnt really notice a difference, but I was always tending to swap out batteries around 5pm when I finished work.
I've just ordered an official Samsung 2000mAh extended battery for my Samsung Galaxy S 2. And I'm starting to play with custom ROMs and kernels. I'll report back my findings when the battery gets here in 2-4 weeks. I'm currently struggling to get through an entire day.. auto brightness, 3g enabled, checking emails every now and then, facebook pushing data down at will, and often with music or FM radio playing through the earbuds.

I"ve got the Samsung Extended Battery with SensatioN Rom with Siyah Kernel.
With bare minimum usage, few phone calls, texting, no 3G connectivity, no Wifi, no music, no gaming, I can get over 5 days.
With normal usage, few phone calls every day, send few texts, internet via 3G or Wifi every now and then, email and weather sync set to every hour, few hours of music here and there gets me little over 2 days.
My heaviest usage was 5 hour continuous gaming without Wifi or 3G connectivity and the battery went from 100% to 12% in that 5 hours.
If you use the display a lot, then forget about getting days of usages on one charge. You might, at the lowest brightness settings, but I never bothered with it. I"ve had my display brightness set at one step above middle ever since I got this extended battery.

could you post screenshot of the " screen on time " please ?
because this is the real challenge for the battery

Better go for original samsung kit 2000 mah....

Please everyone i need numbers
my current stock one gives me max 3~4 screen on time
what about those ??
how many exactly it will gives me screen on time ?
help me on this way please

there is no point other users giving you their max screen time as usage will be very different.
I could say 2 hours of screen time, but I could have GPS connected, Wifi or 3G downloading massive file, music playing and other background tasks doing stuff all at once...
Or I could say 6 hours of screen time at lowest brightness setting while I typed out an essay with no Wifi or 3G, no music minimum background tasks. Almost using the phone as a typewriter.
What you are asking is like "how much farther will 40 litres of fuel get you in a particular car, compared to 30litres of fuel".
It depends on how you accelerate, whether aircon is on or off, are you going uphill or downhill, is it in city driving or highway driving??? People will give you different figures and unless their driving condition is exactly same as yours, the figures really mean nothing.
All you need to know is the extended battery is about 25% larger than stock, there for should give you 25% more usage time.

Stock vs Extended Battery review?

Alright, before anyone tries to bash me for not searching the thread. I want to let you know I spend an hour searching the forums for my question exactly.
Is there anyone out there who has compared the stock 1850 mAh battery to the extended 2100 mAh one?
I have had stock since December. And I am now completely sick of the battery life. 4.0.4 did improve the battery life but it is still dismal. I have the Galaxy S3 for my work phone and that phone's battery runs laps around the Nexus. And that battery is 2100 mAh.
My S3 is always easily getting me through 1.5 - 2 days with more usage than my Nexus!!! Both phones have the same exact settings. (4G always on, GPS always on, WiFi on at home, Google sync on for everything, Skype on all day).
My biggest complaint is on the days where I am not home or at work. Whenever I go out, I don't use my phone so that I can leave some battery there to make sure that I am able to make calls if needed. And even that doesn't work most of the time. My phone will still die before I call it a night. I love the Nexus, and I cannot wait for Jellybean and would like to keep this phone for a long time (even though I have an upgrade available). I am basically trying to decide between extended battery or the external charger with a spare battery option. I would much rather get the extended battery because I am not too keen on carrying an extra battery with me. I would rather put in the extended battery and forget about it. I understand that theoretically the increase in battery is only 13% but to me that doesn't mean **** since the S3 lasts me 2-3 times longer than the Nexus with the same exact settings. So in real world usage, how much of an increase is the extended battery?
Thanks!

I would much rather get the extended battery because I am not too keen on carrying an extra battery with me. I would rather put in the extended battery and forget about it. I understand that theoretically the increase in battery is only 13% but to me that doesn't mean **** since the S3 lasts me 2-3 times longer than the Nexus with the same exact settings. So in real world usage, how much of an increase is the extended battery?
Thanks!

I'm barely able to get through a full day with the extended battery. I mainly use my phone during the day on WiFi. With the activity level that you posted, I don't think the 2100 mAh would be a huge improvement on battery life (maybe an extra hour tops?). Also, I don't like the little hump that it gets with the extended battery attached. I'm running mRom 4.1.1 at the moment.

When I got my nexus in May, I thought I would run the stock battery for a while, but it was terrible for me. In a week, I bought the bigger battery. I wanted to keep the slim profile, so I went with the 2150 with the slightly bumped door, don't even notice the size difference.
The bigger battery makes a big difference for me. Can't say exactly how much longer, but definitely better. I also purchased Juice Defender Ultimate. After tweaking the settings, it reports nearly double the battery. Sometimes it takes a minute to connect to a network if it has my radios off, but not a huge issue for me.
In all, I'd say the nexus is pretty rough on battery. Big screen and 4g, what are you going to do?

Extended Battery 2000mah.. i'm easily getting 24+ hours with moderate usage with data on, sync on, location settings on, 60% brightness..
bigxie 4.1.1 rom + imoseyon 4.2 kernel.. overall very happy with it..
i've had the extended battery for 2 mths now so i guess its conditioned now.
i can actually use my phone and not worry about the battery dying..
i have the s3 as well, but don't really use it yet because i am still waiting for my case to ship from china..

Battery
The 2100 is nice to have just because it doesn't add a lot of bulk. But I only get 18 hours max.

Today I have had my Nexus unplugged for 10 hours and with 1 hour of screen usage battery is down to 25%
My S3 has been unplugged for 12 hours and with 1 hour of screen usage it is at 68%
Wtf!! Battery is so horrible. Google I want to love your bone stock, "this is the ideal Android" phone but this battery is pathetic!!! What the ****.
I bought my phone at $300, I gotta buy another battery for either $25 or $40. They never made the real pogo pin car mount and expect us to buy a piece of plastic for $40. They released the pogo pin dock after 8 months for ****ing $90. Holy ****. This is so frustrating. The first phone I thought I would actually buy all the accessories for, and keep for a good 2-3 years has been a complete failure.

Heavy usage today.
Bigxie JB 4.1.1 ROM + Imoseyon Kernel.
Combination of 4G and WiFi on all day, auto-sync on, location settings on, brightness 60% on, sometimes 100% during peak times of the day.
Overall happy with performance. Ofcourse S3 is better though.. But still love this phone..
How are you guys having bad battery life?

Now that I could live with.. 3 hours of screen time?! Have never seen that on my Nexus, not even when at home, on wifi all day! Is that with the official extended battery or what?
I think I may just have to root my phone and run another ROM and a good kernel. I have been avoiding this because I work for VZW and sell phones for a living. I demonstrate my phone all the time and did not want to be running some crazy mods and having customers saying WTF! lol I guess I should only use the S3 for demonstrations and use my Nexus the way I want to.

Yes battery life is abysmally poor, but it's really a non issue - a package with 3 spare standard batteries and external charger is ~$12 on Ebay, including shipping. They don't last that long, 4-6 months or so, but then I just buy a new package. I'm on my third so far. Love having a couple of fresh spare batteries in my back pocket.
But the battery panel sucks. It's attached with these tiny plastic hooks that break off after a few times use. If only someone would make a more solid back panel. the metal ones are slightly better but much thicker so the phone no longer fit into the dock, and NFC and GPS sensitivity is down the drain.

AW: Stock vs Extended Battery review?
forget about stock battery summary... its useless. try out betterbatterystats (xda or market). it may help you find out whats going on. i can get 23h standby with over 3hrs screenon with stock battery (stock rom 4.2.1 with Franco) which is pretty good compared to what im used to
the only time i got such bad runtime (13hrs+1h screen + 20% left) was with over 2hrs without mobile signal
which is to expected...
imho there are 3 major drainer on every phone: screen, bad mobile signal, some app that prevents phone from deepsleep'ing

I've just got a Hyperion 3800 mah battery best buy I've had it lasted over 24 hours I flash and have an unlimited data plan so I'm always on 4g its a good battery I'll give more as I use I just got it 2 days ago

Can you list whether you are on 4g or on 3g? That's going to be a big difference, on 4g i am only able to get 1:20 screen time, 10-11h standby with lean kernel

AW: Stock vs Extended Battery review?
sry forgot. this was with 3g only as i have the gsm gnex also wifi always on auto brightness everything else off
but with "perfect" mobile signal
BBS tells me i'm loosing 0.4% per h while phone doing nothing.
i also got the extended bat now which gives me about 1-1.5h extra screen on time.
but for the record: its very easy to drain even the ext. battery fast: playing 3d heavy game for 4-5hrs with 6hrs uptime and its at 3%
so no voodoo here

Can you tell me your settings? I have PA 3.0 and AK kernel w/ auto brightness, wifi and sync always on; I get 2h of screen with some browsing, twitter and whatsapp... BBS says I consume 7,4%/h !

AW: Stock vs Extended Battery review?
well don't mistake me - 0.4% was the lowest value i got turning on the phone after idling and starting bbs ..
it will be higher if would do more stuff more regulary i guess
i only sync 1 IMAP account hourly and Google background stuff (incl. being online in gtalk and g+ notifications)
autobrightness on
wlan was connected and always on
BT/GPS off
no special setup just using Francos kernel with stock rom
just check wakelocks and deepsleep values maybe its an app
edit: screen time of 4hrs+ with rss feeds, twitter, texts, chrome and some other rather low resource apps i guess no gaming...

I received today the extender battery from shipshop.
Wow the extended cover makes the phone better IMHO. I'm charging it.
It included a screen protector for free!

The extended battery makes the battery life from bad to "normal". I can reach easily 4 h of screen on time. Stand by is around 18-19 hours, finally I can leave home in the morning and return at night with some battery.
I weighted them:
Samsung Original Extended Battery 2000mAh - 44 g
Samsung Original Stock Battery 1750mAh - 38 g (Which makes sense, we are talking about 45 mAh per gram)
Chinese Battery 1900mAh (Same size than stock) - 32 g (So it's a scam, I'm sure they don't have more mAh per gram than Samsung)
This is the cheap battery I am reffering to http://www.amazon.com/gp/product/B006MQEPW0/ref=oh_details_o05_s00_i02?ie=UTF8&psc=1 (It works fine, but it must be around 1500-1400mAh).
I hope you enjoy this information.

Is NFC affected by the Extended batteries?

Bought two extra batteries for my GS3 and

So today, with pretty heavy usage (at work...checking facebook, twitter, email, web, texting, maybe 15 mins of youtube) I ran through all 100% of my Samsung 2100mah battery from 7:30am until 1:30pm. And I put my 100% fully charged third-party 2200mah battery in right after and now it's at 40% by now.
Unbelievably how terrible the battery life is with the S3.
This is with wifi turned off. with GPS and bluetooth turned off. with not a ton of apps running in the background.
So 1.6 fully charged batteries in 10 hours of occasional use. Wow.
The battery life is like 95% the only reason why I miss my iPhone.
ps. yes I've done the fully charging and fully discharging thing with these batteries.

That's either a bad device or something rogue is running. You are one of the few with that bad of battery.

I have no idea what in the hell it is.
I am rooted, running CyanogenMod 10.
I forgot I had music playing for part of the day, and some internet streaming radio (at like 48kbps).
Either way. 160% battery life cycle in 10 hours of sort of heavy usage is nuts.
In the morning I'll be just reading news on Flipboard and Pulse with brightness at like 60% and running wifi, no GPS running, with no huge apps in the background and it can go from 100% to 90% in like 30 minutes of reading news.

Could be a bad device or maybe some garbage running in the background. I get 14+ hours of average use out of my device.

I usually go by screen time. I get about 4.5 to 5 hrs on a charge with Sync on andeeverything. Running tasks Aokp jellybean

Seeing posts like this make me want to order that battery. Probably will this weekend.

Okay, I know comparing battery stats is almost pointless but I will finally share my experience.
I am a copier technician. I work roughly 8-10hr days. I am literally constantly on my phone. Why? Because I use OTG USB A LOT. My usb flash drive is connected to my phone from the time I get to my first service call, to the time I get in my truck to drive home. I use OTG because I have to use different service manuals through out the day. So I am constantly accessing my flash drive for at least 45 minutes, each hour, every hour until my day is done. By the time I get home, I am down to about 30% or so, give or take 5% maybe. I use it at home to browse XDA until it just about dies. Charge it all night, than do it all again the next day. By the way, on my way to and from work, I play music in my truck. So roughly I get 10-14hrs out of my stock battery.
I have 58 apps installed. And Adobe Reader and sometimes that stock PDF doc viewer bloat is constantly running because my service manuals are pdf.

IDK.... There are so many threads/posts about battery life. I enjoy my Smartphone to the fullest. Run a ton of apps and and many widgets.
I used to try to do EVERYTHING to increase battery life, task managers, Better Battery Stats, going thru cycles of discharging and charging, wiping batt stats, calibrating battery, (which I still do). Underclocking, messing with voltages, etc etc etc.
It got to the point where I was so concerned about battery life I was missing all the great features of these phones.
I use my phone and all its features to the full potential. I bought a cpl batteries I keep charged around me incase I need them. And Overclock and just enjoy my phone.
Watching my battery life constantly and doing everything thing I can to increase it just took the fun out of of having a Smartphone with all these features.

What I've noticed on my att GS3 is that the battery destroyer without a shadow of a doubt is the LTE/HSPA+ radio. With this on battery drains at least 10% per hour especially with the LH9 update. As a test I shut off only mobile data toggle and the amazing battery life I had with my iPhone 4 returned on a more advanced phone. However, that came at the cost of having to shut off the mobile data connection. Mobile data toggle off all day at work 8+ hours and when I got home battery was like 85%.
I believe the data radio is the culprit and I hope they learn how to optimize its battery usage.

Had the same issue with the stock battery I had for 2 months, where just playing music screen off with about 15 minutes of data drained ~40% of my battery in about 2 hrs. Decided to get a replacment, with the same usage I still had 86% after 2 hours. Battery drop has also gotten worse with LTE on the LH1 update

I'd say you've got a bad battery, or a bad phone, or your ROM is bonked - there's no way you're burning through that much juice with normal operation. Maybe talk to your provider and see if you can swap the handset?
Oh, and discharging/charging your batteries does absolutely nothing. Li+ batteries have no memory, so you don't need to drain them - just use them out of the box and they'll work fine.

Might be a bad device or some garbage may run in the background, my cheap Lvbattery the Extended Battery For the Samsung Galaxy S3 [4500mAh the extend the battery] purchase. Eiemall.com fantastic. Easily over a full day

flashed a different ROM than C9/C10, "Triune 2" and started using the excellent battery/setting tweaks in "Go Power Master" and have noticed a pretty decent improvement.
Mainly by having Power Master turn off wifi/gps/location services while the screen is off, and only having my music/messaging apps running and shutting the rest off.
Highly recommend that app.

looks like its about $25 on amazon
but its thicker than the normal battery, so you get a extended back cover with it. sounds awesome but if you (wisely) use a case with your GS3, you'd have to find a different case

another battery life issue

I'm sure this question has been asked before. But I'm coming from an iPhone so Neff help with this.
As soon as I start using the phone in the morning when it's connected to WiFi. Within a second of using it or 2 minutes if we're being realistic. The phone loses 2%. Is this normal ? Coming from an iPhone where 100% would last at least 20-30 mjnutes. I can't seem to find anything draining my phone either !

I think a longer observation period (a full day / through the night) will give a better idea of how your battery performs. Use the default power settings or other batter monitoring application like GSam Battery Monitor and compare it against other users here.

Urban myths and old wives tales. Cycling the battery doesn't "improve" battery life on a Li ion battery. What you are possibly doing is making the battery meter more accurate (placement of the "high" and "low" flags that correlate voltage with "full" and "empty"). But its just a means of measurement, and this doesn't affect the battery life itself. Meaning, it doesn't "improve" battery life any more than messing with the fuel gauge in your car would increase or decrease the amount of gas in the tank.

This doesn't mean anything. The battery % is just an estimation based on battery voltage remaining versus how the phone "thinks" you are going to use it. Comparing 98% on Android versus 100% on iOS is apples to oranges. There is no standard for this, or reason to believe they are in anyway comparable.
As previously noted, 3.5 hours screen-on time with 55% drain (45% remaining) is very normal, even good. A lot of things affect battery life, not least of which is how you use your phone, and cell reception in your area. You will see a wide array of variance in the battery life people get. And since yours seems actually pretty good, I wouldn't worry about it.

Thanks [emoji3] it was actually &37 percent but that's still pretty good with the battery save g options available I should be able to exceed a full day in the event of an unplanned night out !

To be fair, I feel like Apple designs their phone where their first 20% will take forever to drop but as soon as it passed that point it falls to 0. And yes I've seen it shut down at 10, turned it back on it's at 2. Where as this phone's last 15% seems to take forever to drop.

id say thats pretty good life outta the battery. the more you use it the more its gonna drain. and those getting like 6 hours of screen on time are strictly on wifi at an office or something. if your out roaming with LTE and the such your probably not going to get 6 hours...

Intense usage on 4g with lots of camera usage and uploads music and a few phone calls. So far so good! Had more than enough when I got home to leave without changing I case I needed it

I feel the M8, and my past Android phones take a disproportionate amount of time to drop the first few % as well. Maybe not as much as what you are mentioning for the iPhone (couldn't personally comment). May have to do with the saturation charge that occurs when the battery nears full (in fact, you should actually leave your phone on charge for some time after it says full).
Also, the battery meter on any phone is far from accurate. It often can't really be trusted with be within 5 or even 10%. So that would explain why you saw it "jump" down 8%.

Yeah my point was that all these phones' measure battery differently and not exactly accurate so you shouldn't compare Apple to oranges. Oh and the jump in percentages was referring to the iPhones. If anything Android tends to jump up when turned back on lol.
