Three days (66 hours) on one charge!

I bought a used G2x in December 2011 and had okay battery life on the stock ROM. In January I started modding the phone with the Hell Phoenix and later Hellfire Sandwich ROMs. One day my phone started getting really hot and from that point on my battery life got worse and worse until it would only last a few hours. I ordered an 3500mAh extended battery from eBay, but it only increased the stamina of the phone to about 5 hours.
Since I never got a receipt from the previous user I had no warranty. However, I called LG and agreed to have the phone repaired for a fee that would not exceed $100 - they said it would cost between $40 and $100.
Fast forward 10 days and I received my phone back with a "replaced chipset" as it said on the note. And LG was nice enough to not charge me for the repair - kudos to LG!
I noticed that the phone was not getting hot or even warm anymore so I charged the 3500mAh battery to see how long it would last.
Unplugging the phone from the charger Thursday morning just before 8AM I used the phone as usual (light/medium use, but everything except BT enabled) all day Thursday, Friday and Saturday until the phone finally died Sunday morning at 2AM. Yes, that's 66 hours!!!
I'm still flabbergasted that this was possible, especially because I used the phone as usual and made several calls each day.
I'll try to attach a screenshot of the battery use. It was made at the time I went to bed Saturday night so it's not the full 66 hours.
Has anyone else ever gotten results like this or even higher?

Get Juice Defender Plus, it'll toggle your wifi automatically and save even more battery life.
Light usage (sending maybe a hundred texts and a couple web pages loaded) will easily get me through the weekend.

I tried Juice Defender Plus and Faux DS kernel in January but never got any amazing results, but maybe my phone wasn't that healthy back then. Also, I didn't do anything to save battery life during the 66 hour test other than setting the screen brightness to "Auto". I also made several phone calls - as far as I remember it was about one hour and thirty minutes in total.
This really makes me wonder how long I can get in "power-saver" mode (dim, wifi off, 2G, Juice Defender, Faux DS) with the 3500mAh battery. Has anyone tried this?

I would be happy with 12 hours of light/normal use.
Im using the trinity kernel. SetCPU,Juice defender, auto dim screen, Wefi plus,
the only thing that syncs often is facebook on the hour.
and I cant make it 8 hours on one charge.
I rarely use the phone for calls mostly use text for work and friends.
facebook & web through out the day. if i let the phone sit and dont touch it the battery will last all day
I know I am no "light" user. I bought the damn phone to USE it. but I wouldn't say I am always a heavy user. I dont expect to stream for 8 hours but it would be nice If i could listen to the stern show,check Email,facebook,Web & text and only need to charge once halfway through the day then again overnight

Most I've gotten was like 22 hours! -___-

I am definitely a HEAVY user and get around 16-18 hours on a charge. Constantly have Wi-Fi on, sometimes mobile data, gaming such as Temple Run and Angry Birds, and atleast half the time listening to music through PowerAmp. Constant texting, and maybe about 20-30 minutes of calling.
Also, when your cell standby surpasses your display usage, it shows you aren't really using your phone.

Have you popped open the phone to look at the board?
Just curious if there's any variation. Screened on revision number, etc.

I'm not sure what you're trying to get at . As I said I used the phone as I normally do without any "battery saver" methods in place. I never claimed any heavy use during this test.
It'll be fun to try going in "battery saver" mode with the same battery and see if it'll last a week... Well - for ME it would be fun!

Well if I barely used my phone and mostly used it to check the time, I'd be surprised if it didn't last 3 days.

How fantastic - and thanks for the great constructive feedback! I love the warm feeling of knowing that the time I spend sharing my knowledge is appreciated without disbelief.
Really, I don't want to waste my time if you can't read. Just wanted to share my battery experience with stock 2.3.3, non-power saver configuration under normal phone use. And my idea of normal phone use is NOT just checking the time like you say. Compared to my experience when I originally got the phone I'm now getting way better battery life. I believe that the spread in battery performance is wide and far too many people settle with 4-6 hours of use before recharging with the reasoning that it's a dual-core phone and therefore swallows power as was it Gatorade. If I'm wrong and everyone knows that the G2X can go days on a charge then sorry that I brought it up.

Well when your display usage doesn't even show up, yet your cell standby and phone idle are at the top of the list, this means YOU ARENT USING YOUR PHONE. Any way you want to play this out, its not surprising that you get so much life out of your phone since its usually used as a fancy paperweight.
Maybe have your display usage on par with cell standby, then come show off amazing battery life.
Also, the 4-6 hours of life is most common on stock Froyo/GB. Not an issue anymore with custom roms.

Guys, c'mon. You're not even talking about the same thing as each other. A debate is completely pointless.
theking_13 says you're not using your phone enough for the 66h to be that impressive.
PhilipCourtois says he wasn't bragging about how amazing his battery is, but just stating how much of an improvement it was over the stock experience.
Both of you are right. Philip is in fact not a very heavy user, so a longer life for a battery isn't completely surprising. However, phone idle accounts for 21%, whereas everything else accounts for 79%, which is by no means at all "a fancy paperweight". You can even see that the apps that were used account for 39% of the usage at that point, which is more than the cell standby. Furthermore, judging by the graph statistics, the phone was turned on relatively frequently.
Now for something on topic: I'd be interested in seeing someone do a proper test on a 3500mAh battery. Something along the lines of charging it up to 100%, leaving the screen on at 100%, settings both min and max CPU clock speeds to >1000MHz, and doing whatever else you would normally do on your phone in addition to that. Then posting a screenshot of how long that would last them. I predict somewhere along the lines of 9-12h, but it'd still be more informative than a lot of the reviews here. Not to say that the reviews here are unhelpful of bad, because they are very much so helpful.

Good point, but the app usage on GB is extremely inaccurate. I have had my phone on for 3 hours, 27% usage by cell standby, and I played Draw Something for two minutes, and it shows up as using 17% already? ICS graphs on the other hand, are more accurate.
Sent from my amazing G2x running EaglesBlood and Faux.

Hey, you said you get >16h and you're a heavy user. Now I'm not doubting that in any way, but I'm using the same ROM as you, as well as the ELP kernel, which not only is optimized for EB, but is also supposed to be a battery saving kernel. However I get probably around 12h on medium usage. I've tried the faux kernel, and it did give better battery life than the T15 Trinity kernel, but on ELP my device lasted longer (T15 < Faux OC/UV < ELP for me, in other words).
Anyway, my question is did that Anker battery give you far more life over your stock battery, or is your device just lucky when it comes to battery usage? An extra 50mAh is barely anything, but you did mention in another thread that it runs cooler. From personal experience, my phone battery drains faster when it's warmer, so maybe that's it?
I'm really just curious because I've been messing around with battery saving techniques/phone accessories these past few weeks, and I just seem stuck in that 10-14h range on medium (maybe even medium-light by your standards) usage.

My highest is 8 hours. WTF
Sent from my LG-P999 using XDA

How much do you use your phone in those <8 hours? I have moments when I don't touch my phone for hours, and generally I go down at about 2%/h when on standby. So if you ignored those, I'd probably be in the same boat as you.
For example, this is me today:
As you could probably tell, I haven't exactly used my phone a lot today, so I'm at 47% after 11h. However, I tested my battery this weekend by setting my screen brightness to 100%, screen timeout to never, and CPU min/max to 1100MHz/1100MHz. These were the results:
As you can see, my battery didn't even make it to 4h, so it really depends on how you use your phone.

You're right. I never wanted to start a debate - all I wanted was to shed light on the fact that battery life of the G2X can be fantastic - even on stock GB - with the simple upgrade to a 3500mAh, cheap ($9) battery. Before I had the chipset replaced, the phone did NOT last very long and from everything I read on the forums, crappy battery life should be expected if not flashing a custom ROM with battery saver kernel. I'm just saying that that's not true for every phone.

If by "stock experience" you mean the condition I bought the phone in - then yes. But by my standards, the phone is now in as close to a stock condition as you can get - all I did was put in the larger battery. It's running stock GB 2.3.3 with all the T-Mobile bloatware still on it, Google+ on, data sync on, WiFi, 4G etc. on and screen on auto. And I really doubt that LG put in a "special", fantastic chipset when I sent it in for a repair.
Anyway, it seems a real enlightening discussion is on the way once we really start comparing use versus battery life and see that our phones differ dramatically in this regard.

Well I'll tell you everything I did in a sec. But the battery helped maybe 20 minutes, but it is a new battery, so its going to get better results than one that is say 9 months. If it was a brand new LG battery, I'd get the same results.
Now onto what I've done to get this much. First of all, I use EaglesBlood rom and Faux's v0.48 kernel, CM Driver, not DS. I use Wi-Fi constantly, say for about 3-5 hours of the 16 hours that its used. For the most part, I have the network set to only connect to EDGE, not UMTS or HSPA. So 2G for most of the day. Then on the way home, I use 4G for around 30 minutes to an hour, and thats what kills my battery like there's no tomorrow.
Some other things I've done are replaced the Gallery app (supposedly uses battery all the time scanning for files) and use QuickPic instead. Replaced the stock Browser with Dolphin Browser and not only is it smoother, but it doesn't run in the background after I've closed it. Also, turned off logging for the SU app, turned off notifications for Facebook, Play Store, Words with Friends, Scramble with Friends, and auto synching for my Google accounts. Basically turned off background notifications for all apps except Pulse (news app) and Voxer (walkie talkie app).
Lastly, I have my CPU set to 216-816 MHz all the time, unless I play a game and whatnot. I notice no lag whatsoever while playing music and texting/on XDA/ browsing Pulse/etc. I undervolted -25mv across the board, even after what was already lowered through Faux's kernel. Ill post a screen shot so you know what they are. I found if I lowered them more, I'd get reboots sometimes when turning on Wi-fi.
If you have any questions, reply here or PM me. I'll be happy to help.

[Q] Is the battery life really THIS low?

Hey guys.. I'm new here and I plan to stick around..
I just bought a used (for 1 year) Galaxy SL from my friend at a throwaway price. It's in superb condition and everything. Its been a few days, and here's the stuff I've done till now -
1. Immediately upgraded to DDLF2 (India) using Kies. Found some bugs after upgrade. For example, the promised "Video Snapshot" feature wasn't there. Also, the phone rebooted randomly many times in the day and battery ran out quickly (after about 3-4 hrs of moderate usage)
2. Next day, after noticing the weirdness, I decided to flash a custom rom. I heard from many, many sources that Frankenstain Mod and the Bam kernel, along with DDLF2, are the perfect combination for stable performance, nice looks and great battery life. So, following some instructions, I rooted my phone and flashed the rom and kernel. I was (am) REALLY impressed with the final result. I went ahead and installed apps, played games, showed off etc etc..
But sadly, the battery problem still remains. Of course, it has definitely improved a little, but the maximum it can stand till now is abt 6 hours (light-moderate use). Adding to the misery, I am a heavy user. I love playing games, composing music and sometimes doing homework in my phone. I installed JuiceDefender, SetCPU, Battery Saver Pro (which helped in increasing abt an hour). I listened to almost any piece of advice I got. I read through these forums too.
My previous phone running bada OS (Samsung Wave 525) had awesome battery life, which lasted for 2-3 days of HEAVY usage. Of course, I can't expect the same from an Android device, but seriously, is it this bad? And why is this happening? Is it because of -
1. The mod/kernel?
2. Worn-out battery? (i doubt it, every app states that the battery is "healthy")
3. Some internal problem in the phone?
Or is this just something every owner of this phone faces?
Sorry for the long post. Help is greatly appreciated. :fingers-crossed:

1. Its not the mod /kernel. Since I use the XDA-Bam kernel 15 cr5. So far no issues and the battery lasts at least full day. with heavy usage.
2. May be. Even I doubt it.
3. Not sure with the internal problem, but i doubt that there wont be any internal problem as well since you are using heavy applications
with out any lag.
suggestion
1. Do battery calibration
2. Recharge full until you get 100%
3. Clear the battery stats with cwm
4 again drain the battery completely.
5. Recharge it full to 100%
see if it works for you
Press thanks if it helps you

I have calibrated my battery already. It had helped in solving a major problem (wrong display of battery stats). But battery life hasn't been improved in any way.

Yes, it's like that. Most people say "heavy usage", but they don't imagine that people actually use their phone all the time. I'm always streaming music via 3G, reading news articles, auto-sync on 24/7, social-networking, and sometimes playing games. My phone doesn't make it through the day.
People that claim that their phones are lasting 2-3 days usually don't have a data plan, don't use wifi that much, don't play games, and don't use facebook. That's great for them, but I like to use my phone, and when you're making the most out of your Android, it'll run out of juice in 6 hours.
All Android phone are like this. If you're going to use a smartphone, you're going to have to have a charger nearby all the time.

Well said man. Nice to see people admitting android being backward in the battery department. I guess battery technology hasn't advanced much yet, compared to smartphones themselves. Manufacturers have to choose between a thin, sleek design with abysmal battery and a "fat" one with more reliability. I guess they prefer the former, which is leading to problems like this...
And yeah, regarding usb charging, i've seen that it doesn't charge as fast as normal wall charging... Is it normal too?

Yes, that's normal. The voltage is about have as much, so it takes about twice as long to charge via USB cable.

Totally agree with you...mine last less than half a day with normal use similar to yours..it will only last around a day plus if it's in 100% sleep mode

as in my opinion, everything is right with your battery.
u are using ur phone fully, so don't expect to much.
try the better battery stat app, it will show real stones in juice eaters.

I switched from CM9 to GB (Frank mod) mainly due to battery drain. But did not make a difference. However if i keep data off, battery lasts much longer, otherwise it drains around 30% at night. I am pretty sure XXKPQ was much better but don't want to go back. Anyone have other suggestions.

cm9 is not a solution either.
best way is to switch to ddlf2 or xwlf2, bam kernel last version. imo, of course.
and main thing - try to find biggest eater. betterbatterystats will help you.

here is the answer. lookout antivirus. it keeps your device alive instead of sleeping properly. you really need it?
magic locker is not a friend either. try to disable them first, make some discharge cycles without them and post the screens with screen time as well.

different problem
i dont have drainage problem...bt my phone takes a loooooooooot of time to get charged..... i have to charge for about 6-7 hours for the battery to fully charged frm 10%... i did not have this problem befor i used DDLF2

My suggestion: do not install antivirus apps, they drain the battery like hell! For the night battery endurance, just enable the deep sleep function (I use No frills cpu, you can enable the deep sleep from the settings menu) and set the governor and scheduler as you wish.
Battery drain is no more a problem for me since I'm on the Frank's MOD.
Remember to do a full recharge (with the device turned off) and a wipe battery stats for optimize the recharging time.
Cheers

wakelocks means your phone being unable to go to sleep mode for certain periods of time (usually because of retarded apps).
Antivirus on android/linux = scam.
that 3G Watchdog crap, do you really need it? (is the battery drainage worth it?)
I would say your battery duration seems normal, considering you're actually using your phone nonstop plus there's those crap background apps running all the time.
BUT if you wanna be sure about it, why don't you make a nandroid backup (using recovery mode), then factory reset? That should get you back to a clean ROM installation, then calibraty and test your battery overnight (of course make sure your phone is going to sleep mode and is using proper cpu governor). This is the most reliable way to see if your battery drain is related to usage, or just a faulty battery. Go clean, let it sleep, see how much battery it drains.
After this, restore the nandroid backup and clean your phone accordingly (remove crap apps or whatever).
Good luck!

for those on CM9, search for alpha 11 kernel in the general discussion thread...flash that over CM9 alpha 14
i get 3 days of battery on low usage......its pretty similar to ddlf2 in terms of battery drain for me atleast.....and i get ics too....

you can also use droidwall to block all the applications which use internet wihout any reason. they will block un-authorised access to internet and will surely cut a good volume of data usage but remember this works only if ur device is rooted

Hi I'm on paranoidandroid based on cm10 alpha3 and the battery life is at its best 14 hs!!!!
I will try some alpha 4 and check if battery life is improved, else some GB

Large variance in reported battery life due to overheating?

Like many others, I've scratched my head regarding why some seem to be able to get 7+ hours of screen on life while others get only around 3. I know the typical response is wakelocks but those SHOULDN'T affect screen on time much, when the CPU is already awake.
I have noticed that it seems that my device dies much faster when it gets hot, which makes sense, but I've never seen it affect a device to this extent. One time, I fully charged my battery and only got 3 hours SOT merely doing nonstop web browsing on WIFI without putting the device to sleep at all. Yesterday I even froze all apps except the stock ones after flashing PA gapps on Omnirom and my batter was worse than when I had 100+ apps and greenify. Usually I get 3-4 hours SOT a day of normal use on LTE with intermittent, cooler usage. When the device gets hot it also doesn't want to charge nearly as quickly either.
Therefore, I have a simple request: post your best or typical SOT and how often your device gets noticeably hot. I'd like to see if there's a trend between heat and SOT. Or at least vote in the poll. Both would be preferred.

lol, are you serious?
we see a large variance is battery life because we all use our devices completely differently. plus we all have different qualities of phone/data signals, we all use differing brightness for our screems(some auto some not), we all do differing things to set up our phones as we want.. do you want me to go on? and the temperatures, they vary throught the day, depending what you are doing, depending on the temperatures around you. sometimes they can get very hot, sometimes they stay cool with lighter use. i get 5.5-7h screen on time every day. my phone can see temperatures of 88C to 0C daily.

And disabling all apps to take the user setup out of the equation doesn't change things? Or the fact that I only got 3 hours SOT just web browsing? Sure, there's definitely variance involved but it seems like there's more with this device than I've ever seen before. Most devices I've used have been mostly consistent among users and don't have some people complaining about 2 hours versus 7 hours SOT in a short period.
It's easy to say it's environment variables or user error when you're getting 5+ hours every day but when you're someone who's been around the block with Android and phones in general and can't break the 4 hour mark ever, you start to wonder if there's more than initially meets the eye. I don't mean this to attack you, I'm just not sure what else yo do. I've tried undervolting, underclocking, keeping brightness down, greebifying (BBS looks fine), modified location settings, stayed on WiFi, turned off WiFi, removed apps, etc, and nothing helps SOT, only sleep drain.
The bottom line is, have you noticed your battery drains faster when it's hot or is it pretty constant? I'm just wondering if some devices, due to a lower PVS value or some other property of their chip, run hotter and drain more current doing the same tasks. Trying to eliminate the possibility.
P.S. Have you noticed the XDA app modifies or quotes the post above what you press? I have, as you can tell...

ive had g1, google ion, nexus one, nexus s, galaxy nexus, nexus 7, nexus 4, and the nexus 5 now. every one of them has/had great battery life. its the way i setup and use my devices. our use is a huge variable. every single person uses their device completely different. for example in setup and use, you use the crappy xda app, that uses a huge amount of battery, i use the browser, and never install those kinds of apps. many people have facebook installed, i uninstslled it more than 2.5 years ago, i use the browser for facebook. facebook is also a battery killer. i can go on and on. then theres the variances in phone and data signal. bad signals can get more battery drainage, terrible signals can be battery killers.
anyways, you said sleep drains. i bet you have a few badly behaving apps, or you are using the wrong kernel for your device. or, it could just be the way that you use your phone is the reason you don't see 4+ hours sot.

Fair enough. I know the XDA app is bad but didn't think it was so poorly coded that it's a battery hog. The site needs a mobile version IMO.
What do you mean by "you said sleep drains"? My device sleeps quite nicely, I just mentioned that because that's usually the battery life people complain about but that's not an issue here.
I'll try doing a full wipe and not just freeze all my apps and leave just the stock stuff for a couple of days and see if that makes a difference.
Yeah, I wish there was a way to quantify how much signal is killing your battery. Sure, there's the battery page in settings but more detail would be wonderful.
I've experimented with most every kernel but it never really made a difference. I mostly stick to Franco.
Either way, I'd still like to get some crowd data on what they see. Two devices with opposite results is hardly conclusive (even though all your devices have been good, that doesn't necessarily rule out the possibility that there's a bad batch of CPU's or batteries in some Nexus 5's, unlikely as that is.). Everything you've said is valid, but I want to entertain the notion that, while that may be the problem the vast majority of the time, there could be another cause. If I find a bad behaving app on my phone or I just have crappy signal, great, but more data is never a bad thing.

right now.
as you can see ill hit more than 4 hours sot, probably 5.5-6.5h sot. you notice my battery stats, heavy usage, but none of those silly apps eating battery, for me its mostly browser. yet earlier i was at 81C, because i was pushing my device. now cpu temps are around 44C.

That looks like it rules out CPU temperature then, if temperature caused heavy drain you should see a steep slope at that time. Did your battery ever get hot?

This is the first high-end smartphone I've owned that doesn't get hot at all. It'll get a little warm from time to time, but it's never anywhere near what I'd call "hot."
Samsung phones, on the other hand, get freaking HOT. My GS2 would get so hot at times that I could barely touch it, and my GS4 wasn't a whole lot better. My wife's GS3 will be blazing hot in its case when she's just been browsing the web or on Facebook. My N5 is never even close to as hot as Samsung phones have been in my experience.

Hmm, I dunno if I'd say it is painfully hot (thought when trying to wireless charge and use it it gets pretty bad) but certainly quite noticeable. What was the temp in degrees Celsius? I see 70s on the phone and 40s on the battery quite frequently.

Phones that get hot to the touch are actually doing a good job dissipating the heat. Though it may become uncomfortable to be absorbing some of that heat it does have to go somewhere.
Nexus 5 uses aggressive thermal throttling to keep the phone fairly cool and according to Anand has a heat spreader between the SoC and battery unlike the Nexus 4 which caused the two to heat up quicker.
The only thing that will stop me from getting over 4hrs SoT (3.5 - 5 based off usage) is if an application decides to keep the phone awake endlessly. I've seen it happen for Google Search and a few others randomly at times. Reboot or force stop fixes that up.

My nexus 5 battery also seems really crap, and the back gets hot very quickly. Everything else on this device is 100% perfect. Ive tried everything i possibly could (Different kernel, undervolting, lower cpu freq, change governors, low brightness, most connectivity settings off, ok google off, and many more battery saving aspects) yet i still can only get around 2-3 Hours sot with light usage (XDA, web browsing, social media). Is my device somewhat faulty? Or is it supposed to be like this? And normally when i play games, it drains at a speed of a percent per 40-60 seconds.
And please dont go about bashing me, im just a bit curious on how people get around 6 hours sot.

I haven't really had to do this on this phone, but I used to chase Screen on battery drain issues with Cool Tool from the play store. It floats a highly configurable window on the screen that lets you monitor a lot of system parameters including current draw - which is probably what you are most interested in here. I think you can also monitor the temp of the device, the cpu utilization, etc., etc. This lets you play with different settings and what not and get more immediate feedback as to what is happening with your device. In the screenshot, I configured the floating window only to show current draw...should be the pink 182 mA.

Thanks for that link but am I right in assuming most of it's functionality won't work correctly in KitKat? That has been reported with most battery or CPU monitoring apps so far.
I've been looking for something to show me current draw on stock but have only had battery widgets show me the current battery voltage which I don't understand the significance of. Starts at 4300mV when 100% and drops to about 3900mV when nearing empty.

Battery life getting worse, common problem?

Yesterday a post was made to /r/nexus5 on reddit about how battery life was getting worse as time went on. Over 100 people replied saying that their phone was getting worse battery life as well. Here's the link: http://www.reddit.com/r/Nexus5/comments/1yxj2g/battery_life_went_from_insane_to_terrible/ The most people were able to find out was that there was a problem with the Android OS process. Are you guys having similar issues? And do you have any fixes?

Batteries do lose their max charge over time. We're now 6 months aged for the first purchased devices, so it could simply be those batteries are starting to age. They still have years to go, but a brand new battery will always be impressive.
It's one reason why I silently laugh at people bragging about great battery life for a brand new device. of course it will get good life, it's a new battery running optimized software that isn't pushing the hardware as hard as the software 2 years into a device life cycle.

posted by people that know nothing..
as time goes on, you install more and more apps. many apps arent coded very well, and have other issues. anyways, people get more and more of these crappy apps that will drain more and more battery without you even using them. anywho, not a problem here. i get pretty much the exact same battery life now as i did months ago.

great battery life for an "old" device, 5-6 hours screen on time every single day. the batteries life doesnt reduce that quick, and generally youll change phones(within 2 years) before you see the life of your battery shorten.

6 months isn't going to be noticeably less max charge unless the battery was severely abused. Also the phone has been out for 4 months and most are younger.
Here's something to think about: Usage patterns change. People install new apps.
Sent from my Nexus 5 using Tapatalk

Indeed usage patterns play a massive part. And some of which can be completely out of your control.
At home on WiFi I'll get 6-7 hours of screen time.
At home on hspa I'll get 5-6
At work on hspa I'll get 3-4
So at worst case scenario I can lose half of my normal battery usage just based on the carrier performance.

I get about 3-4 hours SoT daily... If anything, that has gone up since I got my device (one of the first batches shipped in US).
I wish I could get 5-7 SoT, with numbers like that, I'm beginning to think I'm doing something very very wrong
Point is... I have one of the first phones shipped out, and my battery life has stayed exactly the same.

High battery usage by Android OS is probably good indication that there are some wakelocks. It has nothing to do with battery being "older".
My battery is great from day one.
Captain obvious mode now:
Posting SoT is pointless and proves nothing. It really depends on what you are doing when screen is on. It is really obvious that it is not the same if you read some book with 5% brightness or play a game.
My SoTs go from 2h up to 7h, depending on usage...

wake lock is main reason makes battery drains so much. try to use greenify to hibernate apps.

LOL. Yep. Give me a day and I'll show you screenies of ten hours of SOT. It'll be BS because to get those results I have to set my phones brightness to less than stock. I also have to set screen timeout to 30 minutes. As well I need to remember to turn the damn screen back on after 30 minutes. I also have to make sure my phone is in my sock drawer doing nothing when the screen is on. It'll still show 10 hours SOT though.

Yeah, the common problem.... My battery just is used for 5 hours.
But there are some fixs to follow:
http://forum.xda-developers.com/showthread.php?t=1168036

I posted my usual screen times on a typical day for me.
Typically I do the same things which are a lot of xda and viewing the verge and YouTube. A few calls and texts.
And from my experience the difference between being at home with WiFi off and being at work with WiFi off is that my battery usually lasts nearly twice as long at home.
I was trying to get across the message that your carriers signal strength plays a massive role on how long your battery lasts.
So say if a mast went down and you get bumped onto one a bit further away (they don't rush when fixing these things unless it's a critical one). You would have done nothing and all of a sudden your battery life has started taking a massive hit.

I'm also having this problem with the android os draining my batter And this started happening within the last week or so.I used to be able to easily get about 30 hours out of my phone, now I'm only able to get about half that. As you can see in the 4th pic, android os has been the cause of a 3h45m partial wakelock, which doesnt seem right to me and is probably the cause of most of the battery drain. the last 2 pics are something that also seems weird to me, as google accounts manager shouldnt take 4% in about an hour. I dont even know why its running that long. Though i know how to quick fix the account manager drain (simply disable it) the android os isnt that simple as i dont know how to see exactly what apps or processes are making it cause a partial wakelock.
Im on omnirom using chaos kernel 9.2

I had a similar issue a while back, and in the end it was Google location reporting within Google now service. Try to switch location reporting off but leave location history on and see if it helps. Also choose Location mode to battery saving.
Turning off location reporting does not affect Google Now functionality...
It can be something else in your case, but this problem was common...

One thing I've noticed as a weirdness is the cache of a phone can get stale and so it gets into some weird loop that drains battery or something and clearing the cache improves battery life. Also sometimes apps can develop bugs or new wakelocks when you do an update so sometimes you have to stay on top of it to track it.

If I did not use some preventative measures to prolong battery life I would maybe get 14-16 hours in a day of usage, I always left wifi on, bluetooth even when not connected, data, force LTE, etc. I did not care because I charge my phone every night. I just find it silly if I get a day usage out of my phone and it is at 50% well assuming you use the phone the exact same as the last day you will use another 50% and it will be dead by the time you get to your charger.

SoT IS A LIE?

Hello XDAres
Read this as a foreword - it's not a must
I've been using my OnePlus One for about a year, and at first the battery was great, but after upgrading to CM12S it seemd like it got much worse. this case wasn't only for me ofcourse.. many other users of CM12s and basically any Lollipop device had complained about a decreased battery life. their evidence to that was their SoT- which used to be (and I'm talking about the majority) around 4-5 hrs back at KitKat days, and had dropped down to 3-4 once they had gotten the 5.0-5.1.1 Updates.
that was caused by a number of things- among of them was the Google Services Wake bug etc.
Now to the point-
My OPO used to get 4.5+ SoT ( Screen on Time) back @ Kitkat days. since the upgrade to LP it went down to 3-4 max.
And then I've tried something-
I simply changed the settings of display, to turn off the display after 30 minutes of screen idle (it was 15 seconds before).
And the results?

}
The suggested conclusion is- SoT is a lie.
If prior to the changes I've made on the display settings, I'd get ~15% @ the end of the day ( say 11PM/23:00 ) and a 3.5hrs SoT, I can now get to ~5% at the end of the day ( again 11PM/23:00 ) by simply raising those values. does it mean that I've used the phone more? well, no, it simply tells us that SoT isn't that trustworthy as we thought.
Opinions?​

So, I have my display off time set to 1 minute and get the same SoT at the end of the day (6+ hours).
Stock CM12.1, no tweaks, no greenify.
Nothing changed since kitkat

It's not a lie, but it is a terrible measure of battery life. Sure the screen consumes a lot of power, but it's not the only thing eating energy, using the phone while the screen is on is a huge burden and especially when I comes to using the GPS there can be a huge disparity between a person that leaves the phone on a counter and a person walking around triggering the sudden motion sensor.

The SOT reported is not a lie, it's completely accurate. You're not thinking about this properly. If you previously had it set to turn off after 15 seconds, then we can be confident that when the screen was on you were actually using the phone and depleting the battery. Since changing it to turn off after 30 minutes we can be confident that after using your phone you'd put it down and the screen would remain on but the battery wouldn't be depleting like it normally would if you were actually using it. Of course you got more SOT, you'll always get more SOT if the phone is sitting on a table with the screen on but not actually being used.

This is the worst premise to start a thread with and to top it off the test you did is so bad I'm at a loss for words. You clearly disproved your point from the beginning. Your normal usage that you had on KitKat gave you more SOT than on Lollipop. Some people have different results though. Changing the display time out doesn't mean anything. You could have as well kept charging the phone not letting it reach 90% and shown a 12hr SOT and the second screenshot you could have reused an old one. No one would know

Have you both seen my suggestested connclusion?
I said that SoT isn't always turstworthy, that is my point, and I've showed that I can use the phone ( a normal daily usage ) for one day and get 3.5 SoT, and the next day I'd get nearly 6hrs SoT. and again, those are the results of about the same usage, the only difference was the screen turn off time.
Thus, we can conclude that people who post pictures of a ~5hrs SoT @ a LP ROM, or in the other and, people who post pictures of ~3.5hrs SoT @ a LP ROM, haven't necessarily have a 'worse/better' battery.
It depends on too many f actors, so we cannot take SoT as a confirmation of a good/bad battery life.

Thus, we can conclude that people who post pictures of a ~5hrs SoT @ a LP ROM, or in the other and, people who post pictures of ~3.5hrs SoT @ a LP ROM, haven't necessarily have a 'worse/better' battery.
It depends on too many f actors, so we cannot take SoT as a confirmation of a good/bad battery life.

SOT is trustworthy just your test is dumb. It's a half baked theory and you're trying to convince yourself you got a good idea. Most grown people don't post fake SOT hence why it's always been a great indicator of battery life especially if usage patterns are similar (that's the key here). Other factors come into play like rogue apps but not the factors you're trying to manufacture with your lame test

I say this to anyone asking how battery life is on a certain ROM or build: the only way to find out is via your own testing.

Yes I read it, but your logic that you use to make your argument is completely illogical. The conclusion is right; there are too many unique factors for each user to take into consideration, so two users with the exact same ROM can have wildly differing battery consumption experiences. I say this to anyone asking about battery life on a ROM or build: the only way to find out is via your own testing.

I see that it is hard for you to say what you have to say without being so rude, for an unknown reason.
I'll still answer you-
Person A- Gets 5.5hrs SoT and he is happy.
Person B- Gets 3.5hrs SoT and he isn't happy.
Both use the same ROM, and both get to 11PM with 15% Battery.
Person A- read emails for a few hours.
Person B- only used facebook a little, navigated for a few minutes, used whatsapp and played Temple Run 2 for about 30 minuets.
both batteries lasted for the entire day.
Person A's phone mainly drained the battery for using the screen- thus the higher SoT.
Person B's phone mainly drained the battery for Data Usage,GPS,GPU etc- thus the lower SoT.
Person A- thinks his battery life is awesome.
Person B- thinks his battery life sucks.
both of them get to that conclusion by checking their SoT.

You're still not getting what I mean and used a very obvious example. I am specifically focusing on YOUR experience, not usage patterns between two different people. You had better battery life on KitKat and I assume your usage patterns and apps have remained generally the same. That's why it's logical to assume Lollipop has worse battery life due to different SOT.
The difference between two people can have too many factors to even bother considering. But judging from your own experiences on different ROMs or Android versions you'll get a clearer idea that your usage will give you. But this assume that the usage is NORMAL not increasing time-out to 30 mins to manufacture results to prove a point

You had to make a thread for this? Everyone knows this stuff.
Which is why when posting SOT stats its common to post your App usage stats along with some description (like WiFi/data usage, Location active or not, auto sync on or not)
I too find your thread absurd just cuz your little experiment has such obvious results it's ridiculous you had to point that out.

I prefer better idle drain rather than high SOT

SOT is a lie for "end users"
I have went up to 8.5 hours of SOT with 40+ mins on call with CM11S-05Q, and on average was getting 6.5-7 hours of SOT with 1.5+ hours call time on 26-32 hours frame.
Moving to COS12 was a bummer, but with COS12.1, just a few days back with some more modification with Amplify was able to get a staggering 6.5+ hours SOT which I had been getting with Custom ROMs like AICP easy ...
So it jots down to the user, how is the user is using the phone, what has he done over the stock behavior of the phone to boost the battery performance, Amplify, Greenify, OS tweaks, myandroidtoolspro etc comes handy.
Again, if you use the phone with stock behavior, you wouldn't be here at XDA.
Oneplus One has best battery performance I have seen in years, since the time of Motorola Atrix 2 and recently Droid Turbo. Motorola had been ruling in battery domain since beginning of android smartphones, cause they were the dudes who made cellphones to begin with, and the only device in which I saw a similar performance is OPO. So SOT isn't a lie, absolutely not.

Lidor, the issue you have is Mobile Radio Active Bug, Google it.

SoT is not intended as a general and absolute battery meter.
It does what is says, it tells you how long the screen has been on after unplugging it from a power source.
Note: Of course when the screen is on consumes part of battery life.
So, SoT is not a lie, is a honest indicator of how long the screen was on.
Why the screen was on? That's the real question, and SoT is not competent to answer.
SoT alone is not enough to compare the battery life between os versions.
What if someone asks: How long will the engine of a car stay on with 10L of fuel?
This is my (educated) Opinion regarding SoT.

sot emm.
