Acceptable Battery life?

I have read many other threads about improving battery life and such but I am still at a loss. My battery in my Epic is only lasting about 5 hours(9AM~1:30PM). I have a moderate signal the whole time and I am using the phone but I only have the screen on about 10% of the time according to Battery Stats(forget where I found this info, maybe spare parts?)
I have turned off Wifi, bluetooth, 4g, GPS only turns on when I open an app that needs it. I really have no idea what I am doing wrong since this seems to be completely terrible battery life. I have also killed the drm service and have found that it did not help my battery life much.
I am rooted and running Syndicate Rom 1.0.2(not froyo since I use a Mac and have not gotten my hands on a pc). I am using Xtreme Kernel clocked at a max of 1ghz.
Any other tips? Should I take the phone to Sprint and ask for a new battery? The phone at this point is only about 3 months old. If this seems to be normal for battery life then I am pretty sure I will be jumping ship and getting a new phone.

Only advise I have is to toggle airplane mode after every boot and switch from the extreme kernel to pheonix 1.43, it has the best battery life by far as will any of the phenix kernels but 1.43 is the best

I got 25 hours of a charge the other day. Had to grab a screen shot real quick before it **** down. Might frame it. On stock dk28 with moderate use, lots of pics...it was on christmas so it was prety well used, trying to escape conversations with in laws.

I'm having the same exact problem. Same ROM and everything. I'm getting absolutely terrible battery life, maybe 5hrs on a full charge. Its ridiculous especially seeing how the nexus s is basically the same phone and gets nearly 20 hrs with no problem. WTF!!!??

Would bet a dollar that your phone is not entering sleep mode properly. Download Spare parts, charge your phone up, unplug it and turn the screen off and wait for like 10-20 minutes and then turn it on and open spare parts and look under Battery History. You will see that it will say Running 100% or something high like that.
This is probably because of something you set up. Either facebook updating every 30 seconds or maybe push email. I dont know.

I pretty much always get at least 24 hours and I work in a basement where I barely get a signal. I leave wifi on all day. I talk for about 20-45 a day on average. I listen to music for a couple hours a day. I play games for a good half hour of my lunch break and sometimes for an hour or two at night. Sometimes I forget to turn my gps off for half the day while I'm in the basement.
I have killed a battery in 6 hours when I spent the entire time downloading and playing games. And I had a battery last 42 hours a couple weeks ago when I was helping a buddy work on a car. We used it to drive some crappy pc speakers for music for about 8 hours in those two days and I spent a couple hours over those two days looking for info to help us diagnose his car.
I have been on Mammon's DK28 for a few weeks and have mostly been on the latest FroYo roms since the leaks starting hitting the public. I ran the same rom and kernel as you guys for a couple weeks, and I don't remember the battery being that bad. IIRC, I was overclocked and still saw 18+ hours of battery life with normal usage.
What are we doing differently? That is the question. Do you have a bunch of widgets and a live wallpaper? I don't. I try to keep my widgets pretty minimal. I have TWC on one screen, a flashlight widget on my main screen, and Pandora and PowerAmp on a third. I generally use a pretty dark wallpaper, too. Something simple and easy on the eyes as well as the amoled. I also keep my wifi on and set it to never sleep wifi. Why? So it doesn't search for a 3g data connection. I have wireless networks I can connect to in the places where I spend most of my time, so I might as well use them. Sure it has to power up the wifi radio, but the wifi radio seems to use very little power when you're sitting somewhere with a good signal. Also, read "How to Train Your Dragon" in the dev section. I have three batteries and generally reset the battery stats on one of them every two weeks. If you only have one battery, every 3-4 weeks is suggested. I always charge my batteries in the charger and almost never plug my phone in (because I don't have to) and about half the time I bump charge the battery after it is finished. Be careful with bump charging as it can reduce the number of charge cycles your battery can take, but can net you 10-15% more capacity in the short term. I rarely discharge my batteries below 15% except for when I'm recalibrating them. If you discharge your battery to too low of a voltage it can reduce capacity. And if voltage is reduced too low, it won't charge at all, but may be fixable with a cadex machine.
Be sure to go find that thread on how to train your dragon. There are some links in there that will teach you a good bit about how lithium ion batteries work and what you can do with them. After that, you need to see what is running on your phone to use that much battery. Is some process or group of process eating your processor?
edit: Look Mom, I wrote a book!

I will try changing kernels and updating to froyo(maybe hijack my dad's netbook).
If this doesn't work then I am going to go to sprint and see if they will swap out my battery. I tried the thing with spare parts and it says time running is 18% since last unplug which seems a bit high but not too ridiculous.
I have read and followed the instructions in how to train your dragon. I am really starting to think it is a faulty battery. I will report back, thank you everyone for the advice.

ok, thank you all for the advice. I am able to get through a whole day now on a charge since changing to Phoenix. Maxes out at about 10 hours as long as I am not constantly on it.
Updating to froyo later today.

Not really going to be helpful for you, but just my observation:
DK28 has MURDERED my battery life. Lots of people have issues with DK28, but the GPS, accelerometer, etc but all that stuff works fine for me - the only problem is the mega hit battery life took.
Let's hope the official release isn't as bad.

DK28 probably murdered your battery life because you forgot to do one of the battery saving techniques that you were using on your previous DI18 rom. Pretty much everyone else is seeing battery improvements with DK28.

I don't think so. I never use GPS, 4G or Wifi and I've always had the brightness auto adjust on.

is my battery faulty?

hey,
Im a new tablet user.I own a nexus 7 and im so disappointed with its battery life that i cant take it anymore so i have to ask.its just been a couple of days since i bought it. the maximum on screen time i get is 5-6hrs.i scrolled over battery life posts of others on this forum and i was shocked to see many of them actually have good battery life which made me worry even more.Maybe its the battery's fault or something.it had some heating issues then i did a factory reset now its fine but the battery still sucks.i have disabled all google apps,location,maps,books..etc all that i dont need but still its no good.please suggest something.shoud i ask for replacement or is it something like the model whose price go down are geared up with cheaper hardware and stuff cos i bought this one recently and this probably came out last year.
The third screenshot was taken after watching a full movie on earphones with full battery.it went down 32 % of the battery.wifi was off.
Please suggest

It's you usage. That's all. Games take a huge toll on battery life on any device.
You have no issue.
Try one full charge with zero gaming. See how you do then. ?

That's about average, as LJ says games really suck battery the most. My typical usage consists of web browsing, XDA forum on Tapatalk browsing, pocket, twitter, fb, etc nothing too heavy really. I get about 4-5 hrs screen on over about 2-3 days. Im usually only on my tablet in the evening and so it sleeps the rest of the time with WiFi and autosync off.
You can always experiment with other ROMs/kernels to see if you can tweak things further.
Also, 5.0 is on the way, you could always flash the factory images for a full fresh lollipop experience. [emoji2]

Battery life has become untenable

I've been having battery issues with my S7 Edge for a while now and it's gradually becoming ridiculous. Despite carrying out a couple of resets and monitoring my usage, my battery life is appalling. It has now got to the point where I'll leave the house in the morning on 100% and within 4 hours, I'm already in my last 15% and that's just with some moderate internet and music usage. I'm having to do at least two full charges a day and then charge it again at night.
I have used GSAM and there is no particular app that is consuming a significant chunk of my battery usage, other precautions such as low screen brightness and closing apps have been taken but this is having little to no effect.
I'm not sure what else I can do so will try and get down to a Samsung repair shop to see what they suggest. When I had a similar issue with my iPhone once, Apple replaced it with a new handset as I was under warranty (as I am with my S7) - have I a fair chance of Samsung doing the same? I love this phone and have had it since launch but it's becoming a massive source of frustration.

I had a similar problems with battery drainage after the update for almost 2 weeks i tried everything and all research came to one conclusion wipe cash partition then factory reset and set the phone up as new no restoring or backups even the google one turn it off set every thing up manually when finished turn the google backup back on and use the phone as you would normally do. Don't be afraid if battery still drains just keep using it as normal and in 3 to 5 days after doze has learned your patterns the battery will be normal again, this is what worked for me your mileage may vary.

Now a days its major problem with smartphones. In mobile their are many types of apps which take more power for running. I suggest you use best app like 360 booster its control your apps and stop apps if its not using. and one more thing make your screen display light low to get long battery time.

after 1 year we need to buy other phone .. that are the rools of the companies

consider providing more info like apps and other usage to assess/comment on your situation. i'm likely not the typical smartphone user (by today's definition), but i'm getting solid battery life for my uses/needs. i'm not the gaming type, no facebook/twitter checking or posting and mainly emails, texts, phone calls. below are screen shots from 1 moderate-to-high usage day (for me); 17 hours on battery, 7 hours screen time, 2 hours of calls, emails (75)/replies (40) 50 text messages, approximately 1.5 hours of screen time was web-browsing. will continue usage and make final keep/return assessment next week. as an FYI, this is a T-Mo G6 that's been sim-unlocked and being used on ATT.

Did you do a restore or a clean install of all your apps? Ive been getting consistently 6 1/2 hours SOT everyday for the past week. Pulling off the charger at 6:30 am and putting it back on the charger around midnight with right about 37-40% left. I did a clean install, no restores.

i know your reply was to the OP, just wanted to confirm that i reinstalled all apps from scratch via the play store as well - was quite painful as i would usually reinstall via TB or backup.

Yeah it was brutal but Im seeing most if us with great battery set it up from scratch. To me that's the best way to go.

Reinstalled from scratch. Android OS/System is what is eating everything on my phone so other apps arent really important.

As much as it will suck, I'd reset it and start over. It should have leveled out by now.

Today was my first day starting with a full battery. Regular use all day long: lots of texts, several phone calls, checking email, adjusting settings, you name it (but no gaming) - a fairly heavy day of use for me. Unplugged at 7:45 a.m. It is now 4:30 p.m. and I have 63% left. FWIW, I'm pretty happy with that.

Today was my first day on a full charge as well, I took it off the charger at 6:30 am and it had some light use throughout my day. As of me writing this post I'm at 51% which is okay but I feel like if it could be optimized a little better I would be super happy with it.
2 hours of screen on time
Seems like the "phone idle" is hogging..

Mine has been on par with my S5 so far. With this having a taller screen (the width is almost the same), I'd say that's pretty impressive.
It does seem a little unoptimized in certain spots. That is, certain processes may impact battery more than others. For example, geotagging. I turned that off because I felt like it was impacting battery. Bluetooth always stays on because I use it for file send and occasionally use it with my headphones when I go for walks.

Update, day 2 my outlook has turned around. I will post at the end of the day but with 1hr SOT I'm at 82% with an estimated 26.5 remaining. (And this was taken off charger at 6:45am.

Going on day 3 and today had some heavy use. Lots of camera use (video and pictures... Cameras are pretty awesome), texting, ton of taking and watching Snapchats and Instagram. Got up at 6am and writing this now with 52%. So far very happy and hopefully will last.

Well as the day rolls into a close I am suuuuuper happy with my results today. This is for sure my current favorite phone now and ideally as doze acclimates more to my behaviour it will keep getting better! Really loving the display though. Quite captivating to look at.
3hr sot (double yesterday's or so)

This is very disappointing.
I have the H870DS variant and I barely get 4:30h of SOT with 1h of voice calls at 15% battery remaining ( using mixed wifi and 4g )
I see that all of you have a high phone idle usage, higher that the SOT. Really this does not seem very good to me.
Having the OP3T, and using it in the same manner, I was getting 1-1.5 hours more that the G6. What is wrong with it ? For me it looks like a software problem

Help Pls

The same happens with mine LG G6. Based on battery stats it seems that the yop battery consumer is Android OS. Did you factory reset? It yes what happened?

Hi. I have lg g6 (h870) for now 3 weeks. Battery life for me is awesome!!:good: Previous phone was huawei P10. With G6 i have 2 days with 5-5,5 SOT. (with P10 i have 1 day with 4,5-5 SOT). G6 heavy use-26hours on battery i have easy 7-8 hour SOT. Stock FW,no root, V10u
No FB,messenger,instagram. Instaled samsung browser. Bloatware uninstal or disabled.

I would say that after sometime i discovered that if you factory reset and then if you do not update the LG apps through lg app updater the phone battery performance gets great!!! DO NOT UPDATE WEATHER AND OTHER LG APPS NO MATTER WHAT AFTER FACTORY RESET!

HELP - Only 3-3,5 hours of SOT :crying:
HELP PLEASE! I've had this phone for almost 2 weeks now and I can't manage to get more than 3, 3-1/2 hours of SOT. I use it almost all day with WIFI and screen brightness at an average of 40% or less all day. Phone idle seems to be consuming at least 15-20% of the battery, is that the problem? The other30-35% is consumed by the apps and 15-20% by the system.

Instead of resurrecting ancient threads why don't you read the ultimate battery thread, plenty of things to try there.

Stock QC2 Firmware - Battery tips?

Hi Friends,
Just wonder if this is normal for this phone, or you guys could give me some pointers for extending my battery life, specifically the Screen On Time?
I have:
- Stock QC2 firmware - I believe this is Nougat with the March security patch
- No Facebook installed (Disabled)
- I am on data about 8 hours a day, rest is WiFi, Bluetooth for my Watch, and NFC is off
- Generally use a black and red theme
- Doing Ad blocking with the AdClear VPN solution
- Sometimes I make conference calls of under 2 hours
- No games, no YouTube watching
With this set I can barely manage like 3 hours of SOT. Is this normal? What am I doing wrong? Any pointers? Thanks!

3 hours SOT is not normal for unrooted stock. I would suggest downloading GSam Battery Monitor and finding out what is hogging the battery. Note that you will need to manually enable the battery statistics permission with ADB for some reason, but after that it will work like normal.
The top two lines should be Android System and Kernel. If you see any non-system app in the vicinity, that is your likely culprit unless you can explain it with normal usage (for example, Firefox is at the top of the list on mine because I surf the web with it)
Alternately, if nothing odd shows up, you may have a bad battery.

The other thing you might take a look at is shutting off the Location setting that scans Wifi/Bluetooth. That is a massive battery killer

Thank you for the helpful responses guys! I'll try GSam Battery stuff... What are your SOTs BTW?
Thanks!

Also my vibration is always on, my back lit keys are always on, and a 30 second screen timeout time, if it helps? Thanks!

Finally, this is the AT&T model with all the bloat disabled.

I'm typically off charge 18 hours and on data the entire time. I do run a Exchange email app that pushes email, my SOT isn't really huge, maybe around 2-3 hours and I also have BT always on and connected to my S3 Frontier. At the end of my day, I end up with with battery around 50% ish.........
Did you recently update, or did you do a clean install? Sometimes the battery can take a few days to settle in

That's pretty amazing! Yes, clean install and updated from MM to Nougat and then the latest patch.
I've got a battery monitoring app installed now... Let's see what it unveils... I'm thinking maybe it's my settings, syncing and etc, cause I NEVER get the SOTs people report on XDA LOL, on any phone really except the Mate 9 I had...

Battery life is SO subjective. The app's installed and the person's usage habits play a massive part in battery life, and you saying that you never get what others are, speak a lot to that.
The built in optimizers in Nougat seem to do a pretty good job at putting unused battery sucking apps to sleep.

I notice one thing, when i connect my Gear 2 by bluetooth battery on phone less about 10-15% less. With out watch and no FB and FB messenger, NFC on, most of day on data, wifi off, 5-6 hours call ( do to nature of my job) i get around 3.5 hours SOT.

I agree bud, so I think my usage pattern must be horrible, cause from the earliest Androids like Droid Incredible to Axon 7 and S7 Edge and others, I never get what people mention. And some of their claimed usage is ridiculous, they say they play games all day, LTE, Videos and still get like 5 hours or etc... Boggles my mind. My biggest battery hog I suspect is my VPN based AdGuard, maybe the vibration, but compared to gaming and etc, they sound so insignificant.

Yeah, that's more like my usage. Without my Watch, this may be the case. I don't use NFC. Thanks for sharing your experiences.

This is a actually normal for USA SAMSUNG battery which is why no1 should get Galaxy S7 on USA carriers battery is even 100 maH smaller at 3500. Battery is always crap usa versions. And I am stuck in them nougat is bad for battery nothing you can do but downgrade to Android 6.0.1 with Odin. Best battery I can upload a vid for proof att Samsung S7 edge battery sucks and so will all USA carriers s8 never buying Samsung again GG. Switch phones best option iPhones have best battery but I hate them. I'd go for a phone with biggest mAh in specs and read reviews for battery. If downgrading doesn't work sorry for all Samsung lovers who read this it's just fact if you actually compare USA version to international. Battery on international is 92 ish hours not even close on USA version +1 sorry for my rant. Second best option I went to zero lemon and got a battery charging case that was like 10000 something maH and I never loose battery because I keep case on entire time makes phone weigh 4 pounds tho

Thank you for sharing your thoughts, bud, I think I would agree, this must be reality. An update for me, seems like getting rid of the VPN based Adblocker has helped battery. Last night, I finally got 4 hours SOT, but that was with the VPN app. Trying without it all day, let's see how it goes.
BTW, hands down, the best battery I have ever seen in the US is on the Huawei Mate 9, even on Nougat. The HUGE battery helps, but legitimately, I was getting 7 hours of SOT.
Thanks guys!

Got the attached SOT after turning off the VPN based ad blocker and using it as needed, rather than on the whole time... Is this closer to normal? ?

I only get 3-4hrs SOT but it is connected to my huawei watch and music is playing when it connects to my bluetooth fm transmitter in my car. I also usually have it plugged in while driving. The best battery life SOT I've seen is on the moto z play. My sister has that phone and she got almost 9hrs SOT. Usually gets at least 7. Someone got over 10.
