Battery sucks after J16 update? Try this!

Like most people, I've had bad battery life since the J16 update. My phone didn't last a whole day [6am-10pm].
I've read and found nothing.
I decided to uninstall the new Task Manager that came with the J16 update.
Since I never installed one before, I thought it was worth a try.
It should be running in the background to check on 'open' apps, right?
UNINSTALLED.
So far, i know my battery has been lasting longer.
You should try this if you don't care about having the new task manager.
You can uninstall using Titanium Backup.
Don't try if you're not comfortable.
If anyone does this, post it up and let everyone know if battery life has increased.

Try a custom ROM

Or, try actually using your phone. Why do people continue to try to pass off "Oh this phone has excellent battery life" when their own screenshots show that they haven't used the phone for most of its up-time?
FWIW, I can get about 4 hours of actual usage, i.e. the total time my screen is on is about 4 hours. That is not to say 4 hours of continuous usage, but rather in total for the whole day before my battery conks out on me.

Agree completely. I get about 4 hours of actual use at best.
I can't even use exchange email cause it destroys the battery.

Than I do not see a point of these threads about "my battery life sucks". I use my phone for my needs, and it lasts me longer since I upgraded to a custom ROM with a custom kernel. I use my phone as an MP3 player during my 2 hr commute, while reading the news, etc. Before I went with the custom ROM+kernel my phone would last 20 hrs at best while performing the same tasks.

Agreed! I actually get 4 hours of continuous use, as well. I thought it was crazy because everyone was talking about getting amazing battery life. Even with battery conditioning, I get the same 4 hours and when I say continuous use I mean it. I check my Twitter, RRS Feeds, Facebook, Browsing, Pandora, gaming, etc. All at the same time and I play heavy 3D games like N.O.V.A not anything like Hang Man. I never get past 4 hours because I use my phone extensively.

This is a serious problem. It looks like the SyncManager has a huge bug introduced in JI6. It seems that the SyncManager will lose it's mind and continuously start pulling data over 3G from Exchange. No emails get returned at this point. Once I kill the SyncManager and run Email I will get all my emails and the SyncManager will run properly again.
When the SyncManager breaks, my battery drains at a rate of 1% per minute and the phone is HOT. I fear what it is doing to my data usage through T-Mobile. I just looked it up. 40 Megs in 4 hours (it was plugged into the charger for 3 of these). 7.2 GB/mo if I let it go for 30 days on the charger.

I'm running Bionix 1.9.1 I haven't used the phone in the past 3 hours and my battery's dropped to 73%

Is that battery meter in the screenshot an app you can download or is it part of a custom rom?

It's part of the ROM. I also believe there is a separate MOD for it.

It is part of Android, so it is available on all ROMs - not just custom ROMs. Go to settings -> about phone -> battery status (or something like that).

You are so right! Let me see those numbers with browser and homescreen on the top and I'd be happy. But I'd like to know if it's OK to remove that new task manager BC it does run constantly in the background?

Out of frustration with horrible battery drainage after the update, i gave in a did a factory restore yesterday as a last resort.
I can happily say that my battery situation has dramatically improved after doing the factory restore. after sleeping for 7 hours, my battery drained ONLY 1% compared to the the night before in which my battery drained 30% over night.
Despite some saying not to use juicedefender, i've had good experiences with the program and I did have it running last night. (paid version)
Regarding mediahub, i have not accepted the t&c's and don't plan to. However download manager (media hub process) is running in my running services.
Currently it has been 14 hours since unplug and my batter is at 25%. I have used my phone heavily for the past 5 hours.
btw, my phone is completely stock.
I am quite happy.

can anyone confirm that removing the Task Manager improves battery?
I did see an improvement stopping the Media Hub and DRM service but it only lasted a shrot time. Now I've been having terrible battery life, I've only been able to get about 15hr with bare minimum use. I rooted lastnight and removed Media Hub. I'm in airplane mode even and I'm dropping 1-2% every half hour.

i dont get it i use my phone all day on wifi then play music at work for 4-5 hrs through bluetooth headphones come home surf the web on wifi for 2 hrs and my battery is still at 35% am i just lucky or ? i dont have the battery problems that i hear soooooo much about ?

Battery DRAMATICALLY Affected by Brightness

**PLEASE READ THE TITLE**
This is not a general battery life thread. I'm looking for comparisons of brightness levels. Thanks.
ALSO: Has anyone noticed a difference when using black themes/wallpaper, etc. I have NOT noticed any significant difference.
Ok, first off, everybody knows brightness affects battery use. However, I've been trying to run my brightness at 30%, which seems pretty low. I figured that can't use much more power than 0%. Still, I've only been getting to about 2pm after charging my phone all night. I'm a heavy user, I like to tinker with my launcher a lot, check facebook, texting, etc.
Today I decided to try 0% on the brightness setting. I'm not crazy about this since it's not bright enough for most situations. I mean, I bought a SAMOLED+ phone for a reason. Anyway, the battery usage seems to be DRAMATICALLY less than with 30%. What's even more odd is my battery usage shows my display using 40% of the battery instead of 50%, which is what I normally see. This isn't a very significant change.
So what about everybody else? Are you guys having the same experience?
UPDATE: I'm up to 7 hrs now and have 67% battery left. Screen on time 1h 26m. This is a dramatic improvement still from 30% brightness.

Ive had my brightness at 100% for most of the day. Im getting great battery life. Im a heavy user and I can get atleast a 1 1/2 days with a single charge. Luckily I hve the luxury to charge over night.

You sir are not a heavy user if you can get 1.5 days with a single charge on 100% bright.
Or maybe a heavy user on calls not browsing or things that use the screen.
on 100% simply 1h browsing, 1h with video, 1 account sync, texting, some calls, check twitter and fb will kill your battery in less than a day, and that is not heavy using.

Can i ask how many hours you have your screen on,
because with 100% brightness i'm lucky to get 3.5 hours (internet/games/twitter) of use out of my phone.

copy and paste from another thread I posted in. This is a very typical day. Now I dont use my phone as much after 6. My phone is currently at 30% from a full charge from friday night.
I make it during the day with 100% brightness. I consider myself an a heavy user.
Ill show my usual day after the new factor wore off.
Unplug at 630-7am
Start my music through Poweramp around 9am at work.(20 gigs of music)
about 20 text/ 30min total of calls
20 or so emails with some attachments
Usually download about 200mb of music/videos throuhout day
Check about 10-15 websites every couple hours(xda app most frequently)
Use Logmein about 10-15min total
Play LIVE holdem Poker roughly 30min total
Youtube/video watching
Some other random things I cant remember
3g/h+ on all day
wifi stays on
brightness at 100%(bright orange/blue wallpaper)
Browser brightness is at 50%
Everyones experience will be different. My original Samsung galaxy s(vibrant) would be dead around 5-6pm. My Galaxy s2 is around 40-50% around 5-6pm. Im experienceing great battery life. My fiance iphone4 would kill my vibrant in battery life, but the sgs2 is on par.

Yes, I too find this very hard to believe. I know if I watch a high quality video on YouTube the battery drain is insane. Of course that is data also but I doubt I could get an hour. My guess is if I just left the screen on for 2-3 hrs my battery would be dead from 100%.

Nope, that's definitely impossible.

I don't believe you, period.
On my s2 I lose 30-40% in 2 hours of not very heavy use on auto brightness. I am shocked that when I surf I can see the battery number (using battery guage) actually ticking down. Device is nice but battery life for me makes it totally useless for a prime device.

I've got display at auto-brightness which is usually around 30% for me indoors. Got display on time of 4hours 16minutes..includes about 45minutes of 3d gaming (modern combat 2) and rest browsing/downloading etc..
total up time 12hours 39minutes...and got 22% left...thats incredible to me, coming from a desire hd, I cant believe my phone is actually still running haha..
EDIT: Oh yea forgot to mention, I got a new replacement yesterday which means I havent even gone through the charging cycles yet, my previous one was superb aswell so fingers crossed this one will be too

Im off today so my typical use is different. Ill repost my battery stats when I get home after work tomorrow.

Well this is helpful, thanks. Sounds like you are getting better battery life than me. Although I would say I definitely am a "heavier" user than you. I used to make it to about 3pm with my GS1. I'm getting about the same with my GS2 if I leave the brightness on auto. That's if I don't use YouTube for more than a few min. I too would like to know what your screen on time is at the end of the day.

Sorry, posted this in the wrong place

That use and that battery it is simply a lie.

The screen is definitely a battery drainer. Don't set the screen to 100% brightness and record 1080p videos. Battery level will be at 0% in less than 2 hours.

Why the f would I lie? Samsung is not paying my bills nor cutting me a check. ill post tomorrow after work my battery stats.

That is impossible on THIS phone with THIS battery! Period!

I'm waiting for those stats.

A screen shot of his display on time along with the graph is what's needed.

Can we get back on OP's original topic of display brightness vs battery life discussion, this is a topic I'm interested in as well as I leave mine on auto-brightness and display is always #1 on my battery consumption list.
Maybe intruda can start a thread called "How my battery life is superior to everyone else's SGS2" and the dissenters can go there and call him out. Just sayin'.

This is my usage today with auto brightness. Mostly at 30%-40% brightness with 45minute gaming and rest browsing. Music. Youtube.
Im impressed.

The Plays Battery can actually rock!

I know a few people have been moaning about the plays battery but I thought I would post a couple of pictures showing how well mine has been lasting over the weekend, I'm highly impressed as I have been using it quite a lot too.

That is 36 hours since a last charge and counting with 39% battery left! during this time I have been using the internet, a few apps, the camera and XDA forum app!
The lowest the Play has latest me is about 7 hours but that is playing 3D games non stop, so anything pushing the gpu will drain the battery a LOT faster than shown above.
So yup, the Play has got a FANTASTIC battery
UPDATE: So far it has lasted 40 hours 8 minutes with 18% remaining

Update, 43 hours with 13% left

Damn i'm jealous. My play doesn't last that long. Did you disable some app's? Ans all sync on manual probably
Sent from my R800i using XDA App

I've got about 150 apps on my phone, Trillian constantly running to keep me online with IM protocols, syncing set to automatic, streaming podcasts with bluetooth and playing games from time to time, often with the screen on for long periods of time. I've been averaging 24-35 hours per charge, FAR better than my old Captivate which wouldn't last a day at any point.

Mine is rooted and I removed a few system apps, nothing major though, I have facebook and twitter syncing every 3 hours, email every hour.
My Play finally turned off at 2%, total time - 45 hours, 7 minutes
I have been using a lot this afternoon so did go down faster during the last few hours, highly impressed as my old samsung galaxy s would never last a day without a charge.

Yeah, I think it just depends on how you use it. For me I don't use 3G at all so that already saves, and then on top of that I selectively turn on/off bluetooth and wifi. I can game for like 3 hours straight and still have 75% left. I think the longest I've gone is 24+ hours with heavy periods of gaming throughout. If you constantly use 3g, wifi, bluetooth, and have a gazillion programs running then ur battery life might be way less.

This is the thing, On the other end of the scale I have only got 7 hours out of it when I was playing games non stop all day but that isn't bad as my old psp would go flat in 3 hours playing non stop.
It definitely depends how you use it but its good to know it can last for almost 48 hours between charges if you want it too!

Hello FK1983, thanks to your post I found the Battery Monitor Widget, which provide more information than the one I had before. I was reading all the post about the xperia play battery because mine was lasting just for half day.
I install this widget and noticed that where it provide the estimate charge use by the phone was showing more than 150mA, this even in standby, while yours was only showing 4mA, base on this I know somethign was running and eating my battery so I restart the phone and now it has been in 2mA while in standby and around 40mA and 60mA while writing msg or checking something else.
Is there any way to know what is eating my battery if I notice the last behavior again? so i can just kill it and not just restart the phone again
Another thing I noticed is that in your picture where you can see the battery information it says "Techno: Li-poly 585/1500mAh" while in my play says "Techno: Li-poly XXX/1200mAh" where XXX is the actual battery charge. Is this indicating that there is something wrong with my battery? I check it just to be sure that it wont be a 1200mAh battery model because of different region market but the battery has written on it 1500mAh. Any help will be appreciate.
Thanks.

Always check to make sure Gtalk isn't running in the background if you're on 3G (make sure your signed out), as it literally destroys my battery in about 6 hours.
And if anyone knows of a precise application that indicates battery usage (outside of the built-in one), I'd love to hear about it!

There's no question that the play has great battery life compared to most smart phones out there. I lost my charger and it lasted 4 days and still wasn't dead when I bought a new one.

any tip?
is a good time in u battery....

The battery mAH settings you can change from 1200 to 1500 in the options, that maybe why some of your stats look different to mine? give it a try.
Regarding running apps, you could keep a close eye on the running processes and see what is running there, or use a task killer or even an "app monitor" that records apps usage.

Folks that report awesome battery life:
Have you applied the 2.3.3 update? I'm still on 2.3.2, and I'm lucky if I get 5 hours of moderate internet browsing before needing to plug in (with about 20% battery left).
Also, in contrast to the OP's picture, my battery widget is consistently reporting between 200 and 300 mA shortly after a reboot. Can't kill any tasks to speak of either. Nothing is running to speak of except homescreen widgets.
Using launcher pro with its built in facebook widget, power control, fancy widget, pandora widget (not playing), winamp widget (not playing), battery monitor widget, google plus widget, and a volume control widget. Running a live wallpaper as well. With all this running, is 300mA a reasonable usage?

I'm on 2.3.3. 5 hours seems awfully short for just web browsing...

I get around 24 hours with 15 hours of Facebook & ebudddy....around 2hours of web browsing and abit of gaming
Sent from my R800i using XDA Premium App

Im on 2.3.3 and i get around 24 to 30 hours facebook and surfing the web for around 2 hours and sending msgs and making some calls. if you are getting 200 or 300 mA i think something is killing your battery. On idle Im getting around 4 and 5 mA sometimes 12-15 mA(I guess something running in the background) and when using the web browser, WIFI on and GPS on im getting around 100-150 mA the most being really bad.

I'm on the R800X. I guess verizon really screwed this phone up.

I rooted my play last night and my battery seems to drain quicker.
I don't know why I havent done anything to phone yet as iv been at work all day. And since I havent replaced all my games yet iv used it alot less today than I normally would but the battery seems to have drained more than usual.
Would a task killer help prolong battery life? I read somewhere that a task manager is not needed with android but im skeptical

Android has a build in task killer, having two will only drain battery. try setcpu and remove as much bloatware as you can(need root).

I just updated my play to 2.3.3 and battery life seems worse for me than 2.3.2. I can barely get through a day of light usage (no gaming, and ard 1 hr's worth of web surfing, switched off most of the updating from apps like facebook, email, pulse etc to manual).
I tried battery monitor widget and my Battery health shows up to be 'null' (my friend's htc desire hd shows 'good'). Would any kind soul be able to tell me if there's something wrong with the battery or the software (mine is stock Singapore xperia play firmware 2.3.3).

How is your Galaxy S4 battery two years on?

Mine? Not very good. Battery lasts an average of 8h with SOT 2:00 (on a good day). I usually take it off the charger at 7:30 at 100%, use it on the way to school and use the school WiFi all throughout the day. Play during breaks a bit and use it to take notes at times, and it's usually dead as a doornail by 4pm. Recharge it, use it to play games and browse the internet and dead again by before 10pm. Battery has already been swapped twice for a new one as both previous ones bulged (one alarmingly so), while on weekends when I use it with data out and about, it gets me to around 6pm, but by the skin of my teeth. How's yours doing?

why don't you provide us some screenshoots of your battery stats?
battery,screen,general usage etc
maybe we can find out why you are loosing so much energy.

If it's still performing well after 2 years, we may have a new breakthrough in battery tech.

Pretty much the same here ....
100% at 7 am ... about 25% at 5 pm ... with 4G connectivity on, work emails sync every hour, whatsapp+viber+wechat sync on.
I have a Galaxy S2, I had to replace the battery after 4 yrs, so I am sure that another year on, I will have to replace the battery for S4 , at which point, I will change my device

My GT-i9505 is also about 2 years old, the battery wasnt that great ever, but lately its been feeling like it drains even faster, so i ordered a replacement battery, genuine one, and their cheap, give or take 10-20 £/$/€ delivered. I plan on using the phone at least another 18 months, maybe 24 months+, no reason not to really, with that battery you can replace, unlike so many other modern mobile gadgets. Having always used either Otterbox Defender or Seidio Dilex on the phone, it doesnt even have any wear'n tear on it, looks like in day 1.

That seems pretty good. Would you say lollipop increased or decreased your battery life?

I'll definitely do so when I drain my battery

Got a bad one today.

@AB__CD
Can you tell us something about your settings? Screen brightness, apps etc

Air view and smart stay stuff off, only one on is swipe to capture, brightness about 50-70, WiFi most of the day, good reception, about 170 apps, 4.4.2 KitKat, i9500 model

If I do an early summary of your settings, this is what I believe:
- you have too many apps installed. The more apps you have on your phone, the more apps are probably syncing with their online services. (Try wakeup detector or better battery stats from playstore)
- A high screen brightness on the S4 is leading to max 2-3 hours Screen on time. Try auto settings.
- You don't have good reception ( look at the grey and maybe also the black signal reception) Switch to 2G Edge network if you don't need H+.
- If you add that your battery is getting old by probably 20% max, than we can say that your stats are quite natural.
Just think about root with only two apps:
- Greenify (for stopping background drain)
- Afwall (for stopping background syncing of apps where you don't need access to internet like games)
You can also try one thing:
Reset (maybe do a backup with helium backup before!) your phone and use only 4-10 really needed apps for 2-3 days. Then you will see how or bad your battery is.

Mine? Not very good. Battery lasts an average of 8h with max SOT 2:45 (on a good day). I usually take it off the charger at 7:30 at 100%, use it on the way to school and use the school WiFi all throughout the day. Play during breaks a bit and use it to take notes at times, and it's usually dead as a doornail by 4pm. Recharge it, use it to play games and browse the internet and dead again by before 10pm. Battery has already been swapped twice for a new one as both previous ones bulged (one alarmingly so), while on weekends when I use it with data out and about, it gets me to around 6pm, but by the skin of my teeth. How's yours doing?

you are going to have to figure out your wakelocks and get rid of any unwanted apps that are running in the background.

Good reception isn't a problem. There was a black bar because I put it in airplane, just changed the battery for the second time recently and just reset it back in December. Too many apps, maybe, I'll continue to do what I can.

Did buying A NewBattery Help ?
My 1 year old i9500 with stock , unrooted rom on lollipop barely lasts a day with very little SOT . So did buying a new battery help ? Also I must say , my stock unrooted i9300 (s3) lasts for more than a day .
P.S . I dont use whatsapp , mostly only stock Apps , no extra apps installed like facebook ... etc .:good:

Nope, not very much.

Gave up. Unrooted, installed lollipop, and factory reset. battery seems improved a bit, see for yourself below, though it has the same issues as every other lollipop phone Android System drains a lot of battery.

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the LG V30 before depleting the battery.
Then, drop a comment if you have anything to add!

First full charge, 100% to 7% I got over 7 hours of screen on time.

Yeah I've heard several YouTubers mention their pre-production unites where giving them very good battery life.
They may be one of the biggest upgrades in the V30, as the V20 had horrid battery life (at least mine did).
If these reports keep rolling in, it will make the V30 much more desirable in my yes.

I have yet to make it below 20%, and I'm seeing over a full day (24+ hours) of usage on a single charge!
This is with my phone sitting on my desk, AOD enabled, and my usage being reddit, instagram, snapchat, allo, and texting with a few wifi calls.
I'm on Day 3 now, I've only charged the device twice(when I first got it, and yesterday morning). I'm still at 46% this morning.

Hoping someone does a full battery drain test with a game or video running until it dies
Seen just one on YouTube but a pre production unit.

The battery life on this phone is amazing! Better than anything I've ever used, even better than my LG G2 which was extraordinary back in the day.

The g2 was extraordinary for it's time, easily hitting 6 hours sot when all competitors were averaging 3.5-4

Like said before best battery life I have ever had on a phone. My GF has a Galaxy S7 Edge and I've always been envious of her battery.
So this battery life was just doing normal stuff, listening to music, watched a few YouTube videos. Spent time on Wi-Fi, decent lte signal.
Amazing. This phone is absolutely amazing and trumps the G6 (a great phone in its own right) in every single way.

Forgot to mention, this is with AOD (with sleep time between 11pm and 6am) and Bluetooth on connected to my moto 360

My results are the same as others, incredible battery life. I purchased this on the 6th and lowest percentage I had before bed was 48%. Off charger at 0600 and put it on charger at 2200. No other phone has lasted anywhere close to this. My S7 Edge was impressive, this blows it out the water. Being a Samsung guy, LG hit a home run with the V30. Tonight I'm not even going to charge to see how long it lasts. Not a power user but aod on, bluetooth on, everything synced, slacker radio, Facebook, Twitter, and YouTube land. Also have to give props to Verizon, the screen protector they offer works like a champ and easiest install. Had a hard plastic outer shell that you drop onto the phone, lay protector on and it slides right in place with no effort.

I'm always amazed that some people get such great SOT. I am getting around 5 hours. For me, this is a WIN. I have old eyes and like my screen bright. I also shoot a LOT of photos outdoors and crank up that brightness to see my results. At the end of my time with the S7 Edge (not even a year), I was lucky to get 4 hours of SOT. As an aside, I owned the Note 8 for a couple of weeks. It held things in memory better than the V30 because it had 6 gigs of RAM, but I really don't notice any lag between the two...

i've still consistently gotten 6.5-7.5 hours SoT over the week now i've had it, even on lte for a good chunk of the day. enabled dev options and turned the animations to 0.5x across the board but even with every social account under the sun syncing and bluetooth connected to my huawei watch, it still performs incredibly. hitting 20% on my pixel I used to shift into panic mode now i'll still play some clash royale 2v2 and not even worry. the only thing I do absolutely dislike is the auto brightness.

So I pushed it today to see how far I could go. I've never gotten this much screen time ever on a phone. This battery is amazing.
And this is with AOD and Bluetooth connected to my watch. Streamed 2 movies and some Netflix shows while at work.

Getting the same battery life. I'm so shocked because I Never get this good of battery life on a phone... Like ever... Lol..
Also, yes, hate the way they handle auto brightness. It's terrible.

I love the battery on this thing as everyone else has said. Never have I gotten over 4 hours of screen time when using a phone . because I use battery hogs messenger/fb/snapchat etc. The standby without AOD has been about the same percentage as my Screen percentage but it hasnt bothered me when I get a full days use out of my phone. My s8 I was using previously i had to fight to get 3 hours of SOT.

Battery life remarkable. Did some tweaks, tho. Disabled 21 packages. I don't use facebook. Dark theme. Everything else is on: AOD, wifi etc. Moderate to heavy use. Just bought it 2 days ago, so was installing apps, benchmarking. Very satisfied with this phone. Coming from Sami S7E.

My first day with the v30. Pretty happy with the results considering it was day one so I was installing apps, testing everything, playing videos, listening to music, etc etc. Phone idle is suspiciously high but I still ended up with a pretty decent SOT and overall usage, so I don't think it's really worth complaining about.

What themes is that

In a full day, I usually see 6-10hrs SOT. Depending on usage of course. But I've never seen an LG flagship get more than 5hrs before! The LCD screens normally kill battery. The Quantum IPS display of the G4 os the most battery inefficient thing in this universe! But nthe V30s vivid and beautiful POLED screen is a battery sipping godsend!
I love this device!
I think the Black Pixel UI theme I use helps a lot too though! I miss OLED since I stopped buying Galaxy devices a few years ago.
