Hi everyone.
I don't see anyone feeling bad about battery nowadays with new update. I dont see any improvement in mine :O
I need some informations from you, can you tell me voltage phone reaches when it turns off by itself? Its very strange when mine reaches around 40-50% voltage goes down very fast and it turns off around 3.2v...
Who's with good battery?
Tell me,
*phone time on battery
*display on time
*wifi time on
i feel like mine is not good i dont know the reason why.. my friend gets 7 hours of browsing(7hrs display on), and i get around 4... it cant last 5 hours with display on.
-- 30 % brightness, bravia off, sync off, auto rotation on --
I saw on internet some reviews 2 days of heavy use :O how?
I tried wiping batt. stats, and gonna try again after system creates batterystats.bin
i did it twice, but slight improvement...
regards
hope this isnt spam for you.
Hi
I have voted 8-9 hours for casual use at low display brightness 20-30%. Auto brightness is allways activated and using it in a fairly light room might increase your display brightness without you noticing this. Could this be the reason you are experiencing such high battery drain with display on?
Heavy gaming:
3D games like order and chaos and dungeon defender that utilize the Andreno consumes up to 30% per hour, that leaves 3 hours of use. Battery history show an allmost 50/50 between display power usage and the game process power usage. Buildin speaker also consumes allot of power.
FPSE that to my knowledge do not use the GPU but utilizes the CPU 100% consumes around 20% per hour leaving 4-5hours gaming.
Light gaming and casual use.
My daughters using drawing programs, playing angry birds or other light weight kids games plus some webbrowsing and email reading consumes about 12-15% per hour leaving 8-9 hours of use with dispaly on.
If you add speech calls on 3G your times will decrease significantly, this is consuming 20-30% of battery per hour depending on signal strengt. This is my personal observations.
Bravia is allways activated and I thought this was only used when watching movies or looking at pictures in the gallery?
It is interesting to read the SE support app installed and the SE recommendations to improve battery live. They mention that if your display is at max brightness it will not make any noticeable difference if you have bluetooth, wifi, data, sync etc turned on as the screen is consuming sooo much power at max they also recommend to use earphones instead of speaker to improve battery consumption. The rest of the recommendations are well known as to turn everything not needed off. The recommendation I like the most is a daily reboot to improve system performance
I like your review.. I got the same result with 3d gaming... 3 hours, but i never had 8-9 hours even with light usage.. Not playing 3d games..
Max. I get is 5 hours but i dont know how, i fell asleep on entry screen on asphalt 6...
Btw. Did u payed order n chaos i cant find cracked version.
3 hours phone on
40 mins display on
1 hour wifi..
Now on 85 %

I began to suspect it's from the battery it self, I reversed to the old firmware .145 the battery was the same, never completes a whole day, 19 hours maximum.
I think its battery too... I bought mine with world generic, and flashed uk generic, its same for me... Has anyone thought that somewhere in system is set battery capacity is example 900, i have read it on this forum in x8... So how to investigate it, my battery dies always ~4 hours display... It went once 2 days, and display time of course 4 hours.

Haha, a nice way of testing it, keeping it running while sleeping :-D 5-6 hours is probably more normal than 8-9 hours, that was when my daughters was using it with a kids drawing program at low light settings, it was not consuming much cpu at no sound was used.
I have bought order and chaos but had shortly installed a cracked version as there were some problems with android marked at the time. I paid for the game but it would not start the download, contacted their support and found a cracked version while waiting for them to fix it ;-)

I got some interesting stuff... I deleted mine bat. Widget, using battery calibrator i can see percentage, 4.2 v full, 3.75 v 46 %, i played 10 min game, percentage fell down, and now i got 35 %, same voltage... Btw. Stock everything.
And calibrated my battery today... I ll post in few days if i got some improvement, but i dont think so...
And 13 min 300 mhz, but display on all the time? Weird.

The batterys voltage will drop allot from 100% to 90% and the voltage decrease will slow down as you are getting closer to 0%. I would guess 3,65 is close to 0%.
The battery % is not calculated from the voltage level but from an internal register in the battery chip that decreases with a value calculated by the battery chip from the exact amount of power used. The battery chip can measure precisly how much power is running to and from the battery.
The android calibration can change this register for example when the battery is getting close to a pre configured safe voltage level, could be 3,65v. It would then reset the register to 0 and the same goes when charging the phone.
If the register show you can have max 5000 units and you are charging the battery and reaches 95% and 4500 units while the voltage show 4,2 which is full, it would then update the register to have 4500 as max level and start to decrese this as power is draining from the battery. If you have 10% left and 450 in the register with voltage at 3,65 it will presume this to be empty and the register would be changed to 0 and battery indicator to 0%. The next charge to 100% should end up at 4150 which would match the exact capacity available for the phone.
The battery will over time slowly degenerate and its capacity will slowly decrease which is one of the reasons the calibration is needed to allways have it show correct battery levels.
The battery is actually not empty at 3,65 but draining it even further will drop the voltage and make the phone crash.
I hope my above explanation makes senses. Had earlier updated and compiled an android kernel battery driver for the old xperia x1 phone. I presume the mechanism for the battery driver in Xperia Arc is the same.

Interesting, the old xperia x1 could not handle levels below 3,65 6i
So I've just recently rooted my Incredible (about 4 months now) and I bought a 3500 mAh battery off ebay for about 12 dollars around the same time. I used to get really great battery life with it. About 2 full days without having to charge. I'm not sure if the battery's getting worse or if this is normal battery depletion for all you other Incredible users.
I'm running CM7 nightly 258, the latest one, and have the newest Incredikernel, just flashed the kernel about a week ago. I'm still pretty new to the rooting game. Before I flashed the kernel I just had the normal kernel for CM7. I was getting about 10 hours of battery before and tried the battery calibration, but I think I did it wrong and got maybe 8 after that.
So I tried running the Incredikernel and was getting between 12-20 hours of battery life after that. My usage is at least 2 hours of Pandora a day using 3g, sometimes 3-4 hours. Moderate to high internet usage, rarely make calls, and moderate texting. I'll sometimes play some games, but that probably equals about half an hour's worth per charge, an hour at most. I'm also running juice defender, too.
With the new kernel I have the smartassv2 governor and have my processor speed between .128-1.113ghz. I think I did the battery calibration the correct way this time. I bumped charged it until it was completely charged. Then let it completely drain till it shut off yesterday. It lasted about 24 hours with the normal usage I have stated above. I then turned it on 2 more times to make sure the battery was completely drained. I took out the battery for a couple minutes and then put it back in. Then I let it charge off until the light turned green. I then booted into recovery and cleared battery stats. Rebooted the phone until it was completely started and then unplugged the phone.
I let the battery drain completely again and it lasted another 24 hours with the same usage I have stated above and I'm now charging again. I turned it back on while it's still charging though.
Is this normal battery life compared to you guys. Remember I have the 3500 mAh battery, but it was off ebay (stated new though). If you could also post you're battery usage and how long your battery lasts, as well. Also any other important info like, kernel, ROM used, CPU speed, etc. I'd like to compare to see how everyone else is doing. Thanks again.
I'm on CM7 right now with the latest Incredikernel. I use the Incredicontrol app to undervolt and set my frequencies from 128-921 Mhz. I have a standard battery and with light usage I get a day and half off a single charge, moderate/heavy usage it'll range from 12-20 hours.
You use any powersaving apps like Juicedefender? Also what do you classify as moderate/heavy usage? What battery governor do you use? Did you do a battery calibration?

I don't use Juicedefender or any power saving app like that. Moderate/Heavy use I mean texting all day making calls, on the internet, playing various games. Don't get me wrong there have been times that I kill my battery in less than 10 hours, but that's when I'm on my phone non stop or on Netflix. For a governor I use smartass, not smartassv2. I did calibrate my battery once, last year when I got the phone. To me what makes the biggest difference is undervolting with the Incredicontrol app. And the phone runs much cooler.
I might try undervolting to see how long that lasts. 1.113 ghz might be overkill, but I have noticed a performance increase. The majority of what kills my battery is the display though when I check out my battery stats. It's always at around 60%. I have the amoLED screen as well.

I always dim my screen as well. If its on the highest setting it'll kill a lot of your battery quick. I used to have my phone over clocked to 1.113 GHZ but after testing different things out I noticed if I lowered it under 1 GHZ there was not much of a diff. For undervolting I dropped the number by 25 at a time until I noticed the phone lagging. hope this info helps.
I have my screen on auto brightness. It's usually at a low bright setting unless I'm outside. I'll try out undervolting, too. I have noticed the phone does run a little bit snappier with the 1.113 ghz though, but I can live with it being a little less if it means better battery life.
I don't know if it's my battery or not though, but everytime I unplug it, it's been going right back down to like 89% within minutes. I understand that you can't fully charge the Li-ion batteries all the way, but I don't know if I'm fully utilizing the battery to it's full potential since it is 3500 mAh.
I might go back to my standard battery and see how it compares. Although I do like the feel of having the extra thickness with the bigger battery.

Charge it while its off or get an external charger. That's the only way to get a true 100% charge from a phone battery.
-My life is a shooting range, people never change-
Yeah, I have been bump charging as of lately(about a month), but I hear it decreases the life of the battery so I've been holding off on doing that.
With my latest charge, I've gotten 1d 14h 49m 20s, with moderate usage which I think is pretty impressive. It's still at 5% and I'm going to let it completely discharge and then charge it off again until the light turns green.
Edit: It lasted me right around 40 hours all together. It shut off so I decided to turn it back on and see how long it would last again. It was at 2% when I turned it back on and I got another half hour out of it which led me to the 40 hours. Do you think that's good battery life with a 3500 mAh battery?
hey guys!
I got my second N7 last week, after I had to return my first unit.
Now it feels like this one has some battery issues. I easily lose ~10% of my battery by watching 20-30 min youtube videos (medium brightness, medium sound, wifi turned on ofc)
Since this seemes very fast, I started AnTuTu battery to figure out if my N7 has some battery problems.
The benchmark is still running, but I wanted to know how long did it take for you to do the benchmark?
After 14 minutes I lost 8% battery in AnTuTu, which would result in 2.9hours until 0%.
(now 14% in 25 minutes)
What are your antutu results? what would an average batterylife look like?
EDIT: AnTuTu Tester Battery Test Result: 362 Points, 2 hours 30 min (100% -> 20%)

nopes, mainly stock apps, some newsreaders. nothing else special.
Just wondering, my tablet doesn't seem to have good battery when on screen time with power saving on.
It's like 10% per 30 minute drain when browsing or playing gta san andreas.
And 10% per 25 mins while sketching.
All of these with the least brightness possible.
Whilst I just performed a battery antutu tester and the result was like 20% per hour max brightness and wifi.
I aslo have battery doctor.optimizer installed.
It was like it from the start. But I didn't noticed it much.
P600 4.4 xxund2.
I get the worst battery life when playing games, likely similar to your findings. And the corner where the S-Pen is, gets very hot when playing games. If it was just playing games I am getting about 3-4 hours of on screen time.
However when I am watching online video or browsing the web, battery life is much better.

It is okay now ( I suppose) after a full charge cycle, 100-0 and 0-100
The gaming usage today was like 3 and half hours with 12% screen brightness and it lasted like from 100 to 51%. And the usage was continuous. (But with power saving on).
Im planning to buy OnePlus 9 pro phone, everything in this phone is perfect for my needs except the battery life. almost all the reviews on the internet suggest that the battery life of the phone is average, and some site say it's worse than that of the oneplus 8 pro, even though both phones have roughly the same battery capacity with the oneplus 9 pro having more efficient display and processor. so do you think it will be improved soon with a software update? and for those how bought the oneplus 8 pro at lunch last year, did you experience the same issue?
It charges to 100% in under 30min...
So seriously, what is it that you do all day where you need to have your screen on for 6-7h, hard usage, without any acces to a power plug to charge it?
Are you a ranger in a Safari Park that tracks Rhino's?
Battery life isn't great, but I top it off for about 10-15 minutes late afternoon (half a charge or so) and I'm good to go. I'll keep my old 30W charger (from my 7 Pro) in my car just in case I'm ever caught with a low battery, but it doesn't seem to be an issue. I certainly welcome any improvements, though.
Usually, ota updates have battery performance improvements...
In the summer i will be moving back home where frequent blackouts are a common thing specially during the hot days, that is why im worried about battery life. and i dont like carrying power banks.
Anyway thanks guys for the replys, and hope future updates would include battery improvements.

I've upgraded from a Samsung Galaxy Note 9. I'm really surprised how quickly my phone has died the past few days at work. Only gets me through about 8hr of listening to podcasts, screen off before I hit 20%. I hope that something improves because I was hoping with this phone I'd be able to get through more of my day without charging.
It's astonishing to me that all the improvements to hardware and particularly power efficiency over the years have resulted in... the same SOT and battery life in general as my four old phone. Progress

They'd rather have the phone charge from 0 to 100% in about 30 minutes so that's their *solution* to the "problem".
Idle or standby battery drain is too much.. Anyone facing that? How to reduce it. My phone was charged 90% in the night. After 9 hrs standby, battery went to 67%. Thats too much battery drain

Mine drains about 5-6 % in 9 h standby. Always-on disabled. Try disabling "listen to hey google all the time", that might be the culprit.
As someone else stated earlier, my battery was horrible when I first got it for a couple of days, then without doing anything, it just got better, like a normal phone. No complaints now. That was my only gripe.
Btw a new update that ends .3.3 seems to be rolling out in India and should further improve battery life. it's great to see they're doing something, hope battery life will get even better.

Same problem here (AOD disabled).
Yeah I now have my phone for 2 days, it's a garbage battery!
It drains like close to 20% per hour of 'light usage', with low brightness only FHD......
Also it drains the battery even when it's supposed to be Idle (no AOD)!
Will probably return this ****.
