[Q] does the battery suppose to drain even in standby mode?

I am concerned about the battery life of my exchanged tab. The first tab I had has great battery life but had some sound issues that's why I replace it. But now I have this new tab but battery is draing fast even not using heavily. I am charging the tab whole night. I did not even has email account setup so its not retrieving any emails. Any suggestions to improve battery life please?

Is your wifi and GPS running at all times?
If you have rooted the tab try using an overclock tool to reduce the load, this should increase the battery life. Until then we are gonna have to wait for a custom honeycomb ROM that increases battery life. If its as bad as you say it is I would try another tablet and hope you dont get another thats messed up.

No the tablet is not rooted but its factory unlocked. How do I know if the tablet is rooted?

It would only be rooted if you rooted it

Mine barely drains with screen off and Wifi on with everything syncing at the same time.. I can go like 2 days average use on my tab so far.

so it seems like there is an hardware issue. Diversion is your tab unlocked or locked?

Forever is an understatement.

I have different battery experience than the OP. I keep my wifi on constantly. On standby with little use (~0.5 hour today), the battery went from 100% to 93% since morning to midnight.

I think it's your unit. I use mine for about a total of 4 to 5 hours a day with wifi and bt at a fixed 75% brightness and when it goes into standby I only lose about 1% every 2 hours. Usually by the end of the day I'm at about 70% battery with a low of 50%.

Have you checked the battery usage to see if any apps are using a lot of battery? (Settings -> About Tablet -> Battery Use)
Mine was at 98% when I went to bed last night and at 94% about 7 hours later this morning. That's with wifi, bluetooth and GPS on, and GMail syncing (but not much else).

all of you guys whose battery has no issue do you guys have tab with locked or unlocked boot-loader. Mine is unlocked and i think because of that battery is discharging fast. Snoopstah i check the settings battery use is screen, browser (which is closed), wifi, android OS thats about it. Please let me know what should i do i have one more day to exchange it.
Thank you all

Exchange it. The battery life in standby mode is stellar. Mine's unlocked too and I lose 2% all night with everything on.

The bootloader on mine is unlocked, and came that way. In either case, that should not affect battery life, though I could imagine how rooting would possibly allow you to install or turn on something that would drain your battery faster (and is left off by default).
Just as an aside, what brightness setting do you guys use on your tabs? Somebody mentioned 75% and that seems super bright to me. I keep my brightness at around 20% or so. Auto brightness is way too dim on this thing. I look forward to some development action on this thing, the ability to customize the auto-brightness levels in CM7 on my Captivate is really awesome.

I have the same battery draining. I can only get 6 hours of straight usage with 20 on brightness. I'll exchange mine today. My zoom can last 8 hours straight of usage

I have no battery issue when in stand by mode and my tab is unlocked and the wifi policy is set to stay on. I drain about 3% per 7 hrs which is excellent.

[Q] Terrible Battery Life

Hi guys, my glaxy s4 has terrible battery life. Like after 5 hours, i need to recharge my phone again. My phone is rooted and on CM 12 (UB ROM). I tried to remove facebook but no luck. How can i improve my battery life? I provided a sceenshot of my battery usage.
I appreciate your help. Thanks in advance

Use BBS and check wakelocks

If ur using it all the way for 5 hours straight, it's normal.

Are you sure? S4's battery is 2600 mAh. It should take about 15 hours or more to make the battery become low with minutes of gaming.. I have S3 mini and its battery is 1500 mAh and it takes about 12 hours or more to make the battery become low.

I can get 5 hours on 60 percent but I gotta be using battery saver with data off when I lock the acreen

take a look at this:

Thanks, i will try it

Gaming or watching movies will discharge your battery in a few hours. 4,5 or 6 hours max. Depending on what you're doing and other stuff like wifi and screen brightness.

Was the battery life always terrible or is it just now?

I'm having a similar problem so I'll use this thread instead of creating a new one. I hope you don't mind.
My battery is draining at a rate of 15% per hour even If I leave it on standby, ocasionally turning on the screen to get a message on Whatsapp of checking the time. It was 100% this morning, 1 and a half hours later, 74%.
After reading on the forums that the cause of the battery drain could be that the phone was constantly trying to get network signal (in cases where the signal is poor, like where I live), I decided to switch on airplane mode. To my surprise, in 3 minutes after this the phone was in 75%. 10 minutes later and I got a 76%. As I write (on PC) it is on 80%.
That's right. The phone started "recharging" without a cable (I know this is impossible, just describing what the display shows me) after I turned on airplane mode.
Any ideas about what might be going on and how can I solve this?
Thanks in advance!
P.S.: It's not the battery itself, as I've bought a brand-new, samsung original battery and the draining was still the same
EDIT: the battery started behaving like this only a few weeks ago. So I'd assume that the signal problem could be helping, but would not be the main reason on why my battery goes down so quickly.

It was terrible from the beginning. I cant replace the battery because my phone is rooted and my warranty is now void. And i won't buy a new battery because i believe the problem wiol not be solved.

You could try that and see if it is a rom problem.
Otherwise try to borrow a battery from somewhere just to be sure it isn't the battery.

Help with new s7 edge PLEASE

Hello,
After reading alot of reviews about the s7 edge battery life i decided to get it. so i got 2 days ago and was really excited about it. the problem the battery is draining so fast and thats really confusing
ive seen screenshots with 50 hours and 60 hours with estimated time. mine barely shows 7 hours. today for example i left the house at 8 with 92% and now im back wth 36% left screen was on auto with wifi
and 3g and sometime gps on. is this normal? am i being paranoid? is it true that the battery will get better with more days of use?
Please tell me what should i do im really worried that its faulty or something.
PS: i did a factory reset before i use it.

Yes, it will take a couple of days for the battery to level out. Do you have the Exynos or Snapdragon processor? What apps are reporting high battery use? Have you disabled any apps?
Sorry for the barrage of questions, but all of these things play a role in your battery life. I recommend GSAM battery monitor and Greenify with aggressive doze, but I will say that 50-60 hours is ambitious. I can usually get 25-30 hours with about 5 hours of SOT. That is with a combination of wifi, 4g, gps and Bluetooth on (android wear), some gaming and facebook, instagram, etc.

Hi thanks for the reply, yeah its my fault i forgot to mention some information
I am using the Exynos model in Netherlands. the screen is always on the top of the list of the battery usage. im using gsam to monitor the battery and i dont think there is anything unusual there android system on the top using 25% or something. im really scared of using anything so it wont die on me outside today i was only navigating and doing some whatsapp calls on the 3g network "not even 4g". i only disabled facebook and using nova launcher and the AOD is off also. im not sure if i should send it back... how many days are we talking about for the battery to get better? i only want somehow a good battery not worse than my old grand prime. as i said i got it wendesday's evening and now its friday and its still bad

If I'm reading correctly, you are losing about 60% in 5 hours? If so, that is definitely excessive even during the first 2 or 3 days unless the screen was on and the phone active the entire time. Can you post screen shots of you battery stats? Maybe some app is causing the problem, but is not being reported as using too much battery.
Some folks say that the different firmwares have different battery usage. Has yours updated?

ok someone told me to turn it off and charge to 100% so i dont have enough data now. but im doing a test now with pokemon go lol
the screen is on about 70% brightness wifi and gps are on and radio is off (i have low cell signal now) and music app playing in the background and now after 50 minutes i am at 89% with screen on all the time. do you think this is good or bad?
i just noticed something in most of the screen shots from other people gsam shows about 3.80v near the temperature but mine show 4.07v does this makes any difference?

That sounds normal for an hour of paying Pokemon Go. It's pretty battery intensive. That voltage is just the current battery charge. It'll drop as your battery percent drops.

Battery life on LG G4 h815

Hi guys
I have just purchased a new LG g4 h815.
I am loving the speed, the looks and everything but I have an issue regarding battery life. I am getting a screen on time of around 2.5 hrs with moderate to heavy use, is it normal for LG g4 though to don't play any games or stuff . Previously I had used a Samsung Note 4 it had an amazing battery life, screen on time was around 3.5 to 4 hrs with moderate to heavy use.
Any suggestions to improve battery life I have turned off location services, auto sync and Bluetooth, screen brightness is @40 % but WIFI is turned on constantly
I have surfed a lots of sites and forums most of them are complaining about the battery life of this phone but still most of them are getting around 3 to 3.5 hrs of screen on time.

The only thing you can do is get back on lollipop. 6h SOT is pretty average score on lollipop

I have basically given up on this phone. Never get any updates (in Norway) and battery is very poor. The worst phone I ever had comparing battery. You should not have to turn off everything and tweak the phone and ask in forums to get good battery time. My father have a samsung brand and don't know **** about android or phones and have he's phone full of crap and never optimized it for anything and he STILL have great battery... Much better than mine. Weird right?
A thing I think, is that this phone struggle with WiFi. I have a lot of wifi disconnects and it gets very hot when it struggles with wifi. Sometimes when im at home I can have 60% left battery and not use it for a while and then suddenly have 40%...

I like this.

Man, i dont even know what are you talkin' about. I just showed that it can last long, not just the 3-4h SOT like a G2. Imperium Rom and Kernel, Greenify, 15% Brightness, Amplified all Facebook(not Messenger) and Google Wakelocks with 3600s. The phone is a 2 momths old H815.

Having just gone though the same hassles, I found the only way to get good battery life is to get the latest version of Lollipop (V10F-TWN-XX for me), root and install Greenify to hibernate hungry apps like facebook etc. I find my battery life is now better than my old G2. I get about 3+ hours SOT and lots of standby time. (Its 10:20 am right now, usage on battery is 3h 35 mins, estimated time remaining is 155 hours, 3 % use in last 3h, 28m screen on time) Previously my battery would have been on 50-60% by mid day, now its in the 90s.
I was almost ready to ditch the phone and find something else, which would have been a shame as I like this phone.
What I tried and found along the way:
- Use the battery charger that came with the phone, the charger that came with my phone had a different plug so I used another brand. This was charging my battery too fast and causing it not to hold as much charge.
- I tried almost every Marshmallow stock rom I could find. Nothing seemed to be that great with the battery.
- I disabled wifi when not in use, location bluetooth etc...went back to almost no apps just to see what was causing poor battery, but determined it wasn't anything other than the system.
Anyway, thats what worked for me. Hope that helps.

Great battery life on Genisys for BL developed by Ignacio R. No root, bloatware blocked, Hibernation Manager on board. It's not heavy used, most browser on wifi/lte, g+, youtube.

10j Batter Drain on T Mobile variant

Every since the update my battery seems to lose a percent every 5-10 minutes the screen is on.

54% in the last 3 hours. This is noticeably different.

Have you looked into whats draining it? i.e. under battery settings or using better battery stats?

Nothing specific. Just screen for the most part and a little bit of chrome. I deleted messenger, and Facebook. Everytime I turn my screen on...By the time I go to turn it off after whatever activity I notice a percent loss.

My battery life has never been what I would call "good", but after the update it has been even worse. Wifi and location off, no facebook at all and screen at auto brightness. The battery seems to lose about 10% an hour and I'm lucky if I get to see 3 hours of screen on time.

I'm getting roughly 0.6% an hour when idle with 10j

T-Mobile. Best ever was 8h SOT with a few percent left in 10d. I am on 10j now rooted. Battery life seems worse but really it's not. Used to get about an hour screen before drops to 99% but now about 20mins. Just seems to measure battery better. This rundown so far was at work in downtown and I was on 41st floor most of the day. I am home now where my LTE is pegged full blast and I could probably pull down at least 5 more hours of this charge depending what I do.

I know it's not a solution in the sense its not solving whatever software is draining the battery but there are aftermarket battery packs for the v20 already that will make the phone last longer.
Zero Lemon specifically makes an excellent aftermarket battery pack if you don't mind the bulk.
I am waiting for a middle man battery pack that's larger than the factory battery but not as massive as the zerolemon.
