[Q] How is the battery life on your transformer

Post your battery usage on your transformer, and how much juice you are getting.
Mine looks like it's draining much.

I had 100% battery when I started using it last night at 4pm used it heavily from then until about 830, which included the firmware update and some angry birds and I was just under 50% by 10pm after 1.5hrs of standby. Didnt plug it in until i left for work after some browsing this morning andwas at 35% then. Hope that helps!

I have an ipad 2 and a transformer and par to par my ipad 2 last longer, but I love honeycomb and it's probably due to the fact that we have real background applications

For my first charge, I wanted to charge it up and then run it down until it died to calibrate the battery. It lasted a good two days, probably 9 hrs of pretty heavy use as I goofed with it constantly. It was hard to get it to finally die, I turned the brightness up all the way and kept it alive to kill the last 5%.

It was draining pretty quickly at first but it improved over time, specially after the first FOTA.
I've been using it on and off over the past 3 days and it has just over 40%.

Just wondering do we really need to run it down till it dies and then do a full charge?

I dunno. People are all over the road on this, so I'll just give you my opinion. I don't think that full discharge of lithium ion batteries is good for them. These aren't the old fashioned NiCd batteries where that was true. The more you use your lithium battery, the shorter it's life. There are people that say otherwise. That said, on an Android machine, I think that the battery calibration needs to see the full range of the battery to be accurate; and it is worth one full cycle to get things working. That's why I did it. I'm not recommending that anyone else do it, that's just what I did with mine.

I thought mine was draining fast at first but I'm on about 32 hours since it was plugged in to get its full charge. Of that a solid 3 to 4 hours of use easy. Currently at 19%

Wouldn't it take a couple of discharges and recharges before the battery gets conditioned?

The other day it was on 100% brightness and light usage I think I got 6 hours out of it. 5 hours in use I'd say. Max brightness and touch intensive stuff like angry birds and playing w/ it FWIW. I'm sure at a lower brightness you could get close to the 9 hour battery life. On the other hand before work I unplugged it at 100% and it sat in a 40 degree car from 7:00am to 5:00 pm and only fell down to 94%.

Asus does recommend a series of full discharges and then basically keeping it topped off from then.

I've been using it almost non stop since 8:00 pm, when it was fully charged. Now, it is 3:00 AM, and at 42% battery life. If it keeps going at this rate, I should have over 10 hrs of battery life. It is on auto brightness. I've been using it to study pdf powerpoint slides, playing some angry birds, and surfing the net with firefox. During the longer studying sessions, I used airplane mode. That probably saved battery life.

I left my transformer fully charged last night and turned it back on this morning to find the charge at 55%.
Didn't seem to be any background apps running that could have accounted for the charge drop, though my wifi was stuck off requiring a reboot to turn it back on.
Anyone else with similar experiences?

I am having the same issue. Last night I had 42% when I put it in sleep mode. This morning tried taking it out of sleep mode and the tablet reboot some time last night Weird. When it came back on it was down to 22%. Dont know but I am getting horrible battery life. Started using it at 10pm last night and by 1 am it was at 45%. Had on auto brightness All I did was surf, and stream music from my server. Maybe I need to drain it down tonight......

That shouldn't happen. Maybe try turning airplane mode on before you go to sleep? Or maybe you need a task manager?
Attached an image of my battery life. I definitely got around 11 hours on one charge.
As for recharging, it seems to recharge to full in 2-3 hours.

I'm finding that during actual use, my TF is doing about as well as my Xoom. However, the Xoom is using MUCH less battery while on standby. Where the TF is burning around 2.5-3%/hour on standby, the Xoom burns <1% on standby.
I'm still on the original build (i.e., haven't had a single update applied) and as noted earlier in the thread some things might have been optimized. And, I'm still burning on average around 3.5%/hour, so that still translates to over 25 hours battery life. Not as good as the Xoom but still pretty decent.
If it gets a little better in standby after an update, though, I won't complain.

I got 9 hours 34 minutes of CONSTANT use. For 4 hours straight I was running a flash application constantly.
I'm doing my second batter run down right now with normal usage.

When mine worked, I used it for nearly 2 hours straight on wifi with the screen on Auto, playing games and browsing the web. It drained 20% extrapolating such I'm getting the 9.5 hours of constant use WITH games. I was pleased until my screen failed on me

When you all drain the battery, are you taking it all the way till it powers itself off or plugging in at a low power state?

i don't have exact times but on my first charge it drained fairly quickly and was below 15% in maybe 36 hrs? with my xoom the first charge lasted 5 days! so in comparison as of right now the xoom had better battery life, but people are saying it gets better so we'll see. i don't mean this as a complaint at all because it doesn't bother me to charge it and i love this tablet. just something i have noticed.
i might add that these times i have given are just browsing, using a few apps and games, but no movies are anything.
aftre seeing a couple other posts in this thread it seems the xoom may just be getting much better standby time.

[Q] Poor standby battery life

I have had my Transformer for about two weeks now, it is unlocked and rooted with the latest stock firmware. So far I am really impressed with this tablet in almost every way except for the standby battery life. I have tried several things including a tasker profile to switch on airplane mode & disable sync with the screen off and an aggressive juice defender profile but the best I can do is about 4-5% drain after 12 hours of standby. I have read several posts regarding battery & standby life and this seems to be pretty typical with what other users are experiencing. My question is why is this so poor?
I am coming from a 7" original kindle fire. On the stock rom that would drain only about 1% every 24 hours in standby. When ICS/Jellybean roms were first introduced that standby drain jumped to about 1% per hour. After several months/iterations the developer (Hashcode) was able to tweak something to get the drain back to something resembling stock (probably 2-3% per 24 hours). Any hope of something like that happening with the transformer?
Gsam battery monitor indicates that when in standby the Kernel (OS) is using the majority of the battery power. Anyone know/understand what it is actually doing? I would think that in airplane mode and deep sleep this thing should drain almost no power at all (system tuner pro indicates that it is deep sleeping just fine).
Sorry for the long post, I think I needed to just rant a bit. I realize that I could power the unit down when not in use, but IMO that takes away some of the convenience of a tablet vs a laptop, even though the boot time is less than a minute. Any thoughts?

I didn't read everything... but endure nothing is running in the background. For instance, Facebook will periodically get your location, download stuff, wake your device up. This greatly kills the battery during standby. I also recommend turning off WiFi when not using it. I lose about 2 percent throughout my 8 hour work day with WiFi on and screen turned off. There is most likely a rogue app preventing deep sleep.

I appreciate the response, but unfortunately I have already looked for any rogue apps, turned off wifi, gps, and auto-sync, then placed in airplane mode. It looks like deep sleep is working fine from what I can see. In my opinion even 2% per 8 hours (6% per day) is too much. I would like to get it to 1-2% per 24 hours. Perhaps I am just too picky but it seems like if the kindle can do it the transformer should be able to.

1 percent is impossible... nothing can do that without completely powering off. All of my android devices, in airplane mode, have about a 2-6 percent drain in standby. You're battery is going to drain. Battery's drain just by having something connected to it. Let alone an entire motherboard. Plus the kindle may have a higher capacity. I haven't looked at the specs but my step mom has the kindle fire and her battery life is horrible. And she barely uses it.
All in all. Weather or not GPS is on or off, or airplane mode, apps can still wake the device. Download betterbatterystats from the play store and see what's using battery. But 1 percent a day is impossible. Period.

Well it will never be doing nothing. Thats impossible. There are always low level kernel/system things happening that require some CPU. Thats why i said a standby drain of 1 percent A DAY is impossible. But 1 percent per 6-8 hours is very possible with limiting background activities/service, turning off Bluetooth/WiFi/Locations and turning off Sync.

the ipad 3 drain about 1% every 24 hours, i know it has bigger battery capacity, but i think it's just a bit more than double our tablet battery capacity, so shouldn't we have only 2 -3 % drain
and yeah i don't use any background syncing or notification, don't leave wifi on when sleep mode, .... the only thing i use is auto-sync but for gmail only, nothing else
does this mean ios has a better sleep mode, like it puts the device into some kind of "extreme" sleep?
and i would be very happy if this tf300 only drain 3% or less in sleep mode / 24 hours, i love this thing but always jealous when it comes to battery

You answered your own question. The iPad 3has double the battery capacity. So no wonder it drains1percent an hour.
The bigger battery capacity if anything tells me it has horrible power management so it compensated by having a much larger battery.

you didn't get my point,
you said this tablet drains 6% / 24 hours in sleep mode
i said the ipad 3 has double battery and drains 1% / 24 hours in sleep mode,
so this tablet has half the battery capacity, but drains 6 times more compared to the ipad,
shouldn't it just drain 2 (or maybe 3) times more? that's why i said i expect it to drain about 2 or 3% every 24 hours, not 6 - 8%
and for your information the ipad does not has horrible power management, or at least does not have horrible battery life, i usually get about 10 hours of web browsing with it compared to 5 hours on this tablet
i'm not praising the ipad or something, these are just true things, in fact i like this tablet better, but like i said i'm always jealous with my brother ipad's 3 when it comes to battery life,

I really don't see how you're jealous when it comes to battery life. I couldn't believe how long this battery lasts. And I'm going to do a test, I'll try not to use my tablet tomorrow and I'll see how much it drains just to get solid numbers. I'll turn of Wi-Fi and everything.

With my first set of tweaks I lost 3% over 9 hours Friday night (my wife's ipad 2 lost 0% over 12 hours incidentally for comparison). With my second set of tweaks last night I only lost 1% over 13 hours! I made a few more today and we'll see how it does overnight tonight.

I believe the key is to chase down the programs that are waking the device while the screen is off. My methodology was this:
1. Install a battery monitoring program that lets you view what is using the battery and specifically what programs are waking the device and the number of wakelocks per program. I personally use Gsam Battery Monitor but I believe a lot of people use Bettery Battery Stats for the same thing.
Before going to bed I would charge the device to 100% and then unplug it without turning it on. I would then let it sit usually overnight and until I got home from work the next day (16-20 hours).
2. Open up the battery monitoring software and look at how many times each app woke the device. In Gsam this is done by clicking on “App Usage” from the main screen and then selecting “View Num Times Waking Device” from the drop down menu.
3. Once you know which apps are waking the device you need to figure out what to do about it. It seems that you can control some of them typically by going into the app’s settings and turning off any background checks/updates and turning off any notifications. In my case the main offender was an ebay app that I had installed when I had a few auctions going on last week. It had woken the device over 600 times in 16 hours or so because I had push notifications on! That one I simply uninstalled.
Some programs I could not get to stop waking the device no matter what I changed in the settings of the app. ScoreMobile “TheScore” was one of these. No matter what I did it would wake the device 4 times per hour. Programs like this I chose to freeze with Titanium Backup until I can figure out what to do with them.
I also turned off automatic updating of my google apps, unchecked all 3 boxes under Location Settings”, turned off autosync, turned off calendar notifications, and added a tasker profile that places the tablet in airplane mode when the screen is turned off and turns it off when the screen comes back on. Some of this may be overkill for the time being but right now I am working to get the consumption as low as possible over a 24 hour period then I may start turning things back on until I reach what I consider an acceptable drain.
Sunday night to Monday I went 23 hours with 3% battery drain but I had installed ScoreMobile that day and like I stated above it had like 91 wakeups over that time. I froze that app last night and we will see how it does, I think I should be around 2% for 24 hours.
Let me know if you have any questions.

I agree with Collin. You have trace what's chewing the battery. But I also wanna say I have clean ROM installed as well as the tf700 kernel. So that is prolly playing a huge role in battery life. But straight stock, good luck lol.

Battery Calibration for Razr HD

I've recently noticed that my 3 month old Razr HD drops the first 5% in a couple of hours, and when I get to around 14%, I lose the next 10% in about 30 minutes.
The funny thing is my phone can stay at 1-2% for another 30-120 minutes. Yesterday I got home at 1% and 2 hours later the battery notification light was still flashing at me to plug it in at 1%. It literally powered off as I was plugging in the AC adapter.
So I ask, are many people using a battery calibration app? If so, which and what are your results.

I use Battery Calibration by NeMa, works great... I usually use it every month or so, and I let the battery drain all the way first, then charge it to 100% and use the app. Unplug my phone and reboot. I have been using this app for years and its been working great, I have a Razr HD now also and of course you need root.

Charging duration ?

Hi guys, I have my phone a few days now but usually let it charge over night when iam asleep so when i wake up, i just unplug and off i go. But last night the battery was still on 30% so i figured i would wait until today and charge it! I had read it takes a hell of a long time to charge but surprisingly my phone went from 4% to 89% in just under 2 hours! A few minutes later i noticed the led had turned green so i was like "what the hell, no way can it be fully charged that fast" ....... and it wasnt ha it was now on 94% so i have no idea why the led changed to green but it had gone from 4% - 94% pretty fast so i was happy and expected the last 6% to charge pretty quickly . The next time i checked my phone 2h35mins had passed and it was now on 99% but then it just seemed to come to a halt. I would check the phone every 5 mins expecting it had reached 100% but nope. Over 3 hours had passed before it finally hit 100% but the icon beside it read 'still charging' so i decided to leave it until it was fully charged . Well its now 3 hours and 30mins and the phone apparently is still charging lol
How is it possible for it to charge so fast up until it reached over 90% and then slow down DRAMATICALLY ? Is this normal? plus why the hell did the led turn green long before the battery was fully charged?

Always the last 10% takes almost 20 mins to charger whereas 0-90% can charge in an hour or an hour and ten mins.

20 minutes??? Mate it took almost an hour just to go from 99% to 100 lol Whilst on 100 for almost an hour it was still allegedly charging so whilst waiting for it to be fully charged i just lost patience and unplugged it as it was on 100 so figured it must be fully charged even though it was still charging! So in total the phone was plugged in for almost 4 hours and was still charging at 100% when i unplugged it yet it had gone from 4% to 94% in barely over 2 hours lol

That is kinda strange bro. Y don't u calibrate your battery by downloading an app from the play store or let your battery drain to 0% and shut down and then charge from 0-100 and check the time.

Good idea man,might leave it drain completely and see how long it takes to reach full charge! I suspect it should take a long time but it was just weird how not only did the led turn green before it was fully charged but it had charged damn fast up until that point and then just slowed down massively although its not a huge concern as the battery life is fairly good

Note 10+ battery drain

I've had this phone for two weeks now and the past few days every time I charge it to 100 it instantly drops to 99 after 2-3min of use. I'm not running any heavy programs either if I just have the screen on it will drop. In the screenshot below I had 13min of use and it went down to 98. Is this happening to anyone else? I don't have power saver mode on.

I'll check it out next time I charge the phone.

Seems to be just about right

If you're not getting good enough screen on time and did factory resets already, try reflashing the system. It worked for me.

Mine does the same exact thing. My note 9 never had this issue and I'm only seeing 3 to 3 1/2 hours on screen time..
My samsung SM-N975U battery averages 1d 0h 0m (19h 50m 0s active usage) on a single charge.

My note 10+ goes from 100 to 97 in about 5 minutes. Current situation -
upload
The last thing I'll complain about is going from 100% to 97% in 5 minutes with this type of battery life.

I am in a situation where it feels like its draining faster then it should, but Im also using it more than I should, so I dont know if a phone issue or a me issue. Im gonna do a reset to see if the results remind.

I realized that the Secret for obtaining high amounts of battery life (screen in time) is if you consistently use the phone.I found that I can easily get 10 hours if I'm constantly using the phone to the point where the screen is on for 10 hours. The second I put the phone to sleep and I don't use it as much is when I start heading 6 to 8 hours of screen on time. It's weird how they've implemented this but,
I now just use my device without even concerning myself with the battery life for screen on time because it doesn't really matter. In the back of my mind I know I could get 10 hours if I actually spent that amount of time on my device with the screen on. When it comes to regular usage 6-8 hours on a device that lasts a day and a half sometimes almost 2 days I don't think it's anything to complain about

The problem is that your phone like mine must have came with 4300 or less mAh ... Most likely less ... Mine has 4280 mAh I am very pissed at Samsung for that since my hauwei p30 pro phone have almost 4800 mAh so it spends 8 hours in 100 percent until it starts to decrease the battery that is why so many fear hauwei I guess it was my first phone from then and it's amazing how it is superior to anything I have ever seen before ...
