Hi everyone
My question is for techy people in this forum.
According to you why standby time of TF is so bad when compare to ipad2.
Is this software or hardware related problem?
Is it fixable?
Thank.

Software problem, IIRC mainly related to the keyboard dock (dock will drain battery when it should be asleep). I still get several days of standby time, which is far more than acceptable. I don't need 2 week standby .
This post needs to go in the proper forum, however.

Sorry, I though this is related to development.
So you are saying that honeycomb is bad by design to battery? Because all honeycomb tablet have the same problem.
There is some thing about standby mode that consume for power than ipad, but why?
It is nice that the tablet does not run out of battery when you really need it.
After leaving my Transformer untouched for about 4 days last week, the battery was sitting in the 80-ish percent area. Seems like pretty damn good standby time to me.
Standby time depends on whether you have the pad docked to the keyboard or not.
If you keep the two separated the standby time is pretty good although I haven't timed it.
If you keep the tablet attached to the dock then standby time for the dock is greatly reduced as it seems to keep charging the tablet until it drains to zero even if you started with a fully charged tablet. It is a very annoying problem that no-one seems to have found a cure for yet. If you let the dock discharge fully some people have found it impossible to charge again.
I am comparing TF and ipad2 without the dock for the obvious reason.
And how long is the iPad 2 standby time?
After using a HTC Desire with poor battery life for the past year I find the standby time for the Transformer to be fantastic. I'm able to use it a bit each day for at least about 5 days. Nothing heavy, but the fact that I can pick it up after a few days of no use and it's still got a decent charge is impressive to me these days.
never used an ipad/2 for extended period of time but stnadby time on the asus is pretty good. what i find helps greatly is if you plan on leaving it in standby for a awhile, then its best to turn off WiFi as it'll help save battery life even more.
i had it fully charged this morning and unplugged it to take to work. Unplugged it around 730am, powered it on and turn off wifi and let the screen timed out. Finally turn screen on at like 130p and the battery still shows 99%
My stand by time was horrible on stock 3.1 I don't why. Once I rooted and installed Prime and OC kernel at 1.2ghz I get much better standby time. Almost comparable to my Ipad 1. Battery life seems to be better too as compared to stock 3.1

let the wifi shut off when the tablet goes to sleep, it's something iOS does by default and turning off radios will make the battery last a lot longer.
also, if you are going to leave wifi connected, the less widgets and applications you allow to pull data (or adjust the intervals they are set to sync), the longer your battery will last. iOS also is a very passive OS so when you put an ipad to sleep, everything is basically shut down, android allows apps to keep running if you have set them to sync data (ie, twitter, facebook, etc) which will also consume more battery.
the dock issue is an issue. but undocked, mine will last a week or so with light/moderate use, then again i generally charge it at night anyways.
and yes, this should be in general section, it has nothing to do with development for the device, you are asking a general question about the device/platform.
I just took my transformer on a 5 day trip, fully charged to start with, and i didn't bring the charger. I probably only used the tablet 3 times for 15 minutes, and the rest was standby. When i got home and plugged it in, it was down to 2% battery, just about to die. That is just unexceptionable. And iPad 2 under slimier circumstances would have consumed maybe around 20% of it's battery life?
I read somewhere that the new samsung galaxy tab 10.1 is rumored to have up to 75 days of stand by. I don't believe that at all, but if they are claiming that, i would assume that i would last much longer than 5 days. (plus i played with one the other day in best buy and it just feels awesome in the hands)
conclusion: hopefully future updates will help out with the transformer's battery life and stand by time.
Thread re-opened and moved to General.

Which is your WIFI policy?
I have it on WIFI off when screen off, and stand-by time is pretty good. I guess that if you need WIFI always on it will adversely affect your battery usage.
Regards.
Its not a Honeycomb issue its a Asus issue. I have a Samsung 10.1 and the stand by time is much better then the Asus. The stand by time for the 10.1 is about 7 hrs and it eats up only 3%. Also, the wifi policy on the 10.1 is set to stay on when it goes into stand by mode. My TF wifi policy is set to turn off when the screen is off and it still eats more battery life then the 10.1. I pretty much have the same apps on both tablet.
Yeah, I have mine set to turn off the wifi when the screen is off (pretty sure this was the default setting), and my standby time is much better than I was expecting (as per my post on the first page). Given the drain I've experienced, I'd expect it to last 2 weeks or so on standby, which seems pretty good to me.
It could be that your wifi disconnect policy is not set to go into standby when the screen goes off. Don't worry, it waits 15 minutes before actually turning off the antenna. But there is a bug where it defaults to "Never" after being charged (including the dock), or after a reboot:
http://code.google.com/p/android/issues/detail?id=16720
I get a few days out of mine, but I don't give it much chance to be standby, I use it regularly in the evenings.
Hi,
I am sorry, I think I didn't well explain it.
It is the fact that TF has less standby time than ipad2.
But, my question is more about Technic.
Ipad2 does email sync with wifi always ON beat TF wifi off.
But why? There is some app working in background? Why it need to be in standby mode?
I still hear email notifications even with Wifi policy set to turn off when screen is off. Definitely a software problem. In regards to the dock issue, ASUS needs to make some changes to Honeycomb so when it knows the dock is plugged in, the power saving features still kicks in when on standby despite the tablet being charged. It probably assumes the dock is actually a wall charger and doesn't kick in any power saving features. (default behaviour set by Google)
I think the main question in this thread needs to be why are people leaving their Transformers in standby for soo long!!
USE YOUR TABLET EVERY SECOND GOD GIVES YOU AND YOU WONT CARE ABOUT HOW LONG IT WILL LAST WHEN ITS ASLEEP

Hi Guys,
How is your battery performance going? We have three 64GB 3G Lenovo tablets in our office and we are struggling to get two hours usage out of any tablet. Even just leaving them in standby mode will drain them fast (less than a day). I have the acer iconia A500 and can leave that around for days and still have some juice when I pick it up again. Any idea why battery life is terrible on the Lenovo? We are all running different apps. Mine is pretty much just running stock with a few ebook reader apps.
Cheers,
SB
Something is wrong with them if the battery life is that poor. Presumably with the hardware if you're running things mostly stock. Strange, though, that it'd be all of them and not just one. Mine gets 8 solid hours of medium to heavy use, no sweat, and other people have indicated theirs get about the same. You might want to contact Lenovo's tech support (though just a word of warning, they have kinda lame tech support nowadays...).
I've got a 32GB no 3G tablet that continues to surprise me with it's battery life. I'd read plenty about folks with crappy recharge and usage times.
Mine will still have the same charge the next day if I don't put it in the dock and I generally get 7-8 hours out of a full charge, even over the period of a few days.
The old 'cell-standby' battery drain disappeared a while back. Don't know why. Don't miss it at all.
Under normal use for me (sketchbook pro, browsing, and an occasional game) I get about 8-12 hours of use (basing that on the screen on %), with 3-4 days between charges. Something is certainly up with yours, what is listed under settings>about tablet>Battery Use?
Info
Tablet 1:
Battery 69%, 7 hours on battery, maybe 20 minutes use. (Mobile broadband turned off)
Screen 39% (on auto brightness)
WiFi 26%
tablet Idle: 23%
Cell Standby 7%
Android OS 7%
The other two are not available, but as a colleague ran out the door, he mentioned that his cell standby was 33% despite mobile broadband being turned off.
Thanks for your feedback so far.
Mine (16GB version) lasts for 4 hours when it's REALLY busy, that means when I stream videos over wireless.
Otherwise...after a full day of normal usage I'm back from 100% to 40%.
Anything else I think is not acceptable..I suggest you guys have your tablets replaced.
Wait, I just had a thought. Are you guys using the keyboard folio with the tablets? If so, there's something you should know. After putting the tablet to sleep, you can't close the folio for another 10-20 seconds afterwards. Otherwise, the optical trackpoint ends up detecting motion from the tablet being on top of it and it wakes the tablet up repeatedly while the thing is sitting closed. So you have to put the tablet in sleep with the folio still open, let it sit until it goes into deep sleep, wave your finger over the trackpoint to make sure it has (after 10-20 seconds), THEN close it up.
my battery is good on standby (with wifi sleep).
Your battery drain is because of cell network. use airplane mode !
I RMA's 2 of them with the same symptoms, took all day to charge, discharged way to fast they ended up having both bad motherboards and bad batteries. I called up lenovo sent them in and had to wait about 3 weeks for the parts to come in, but they have been working incredibly well now.

That sounds very similar to the three we have. 6-8 hours to charge. Less than an hour of use to discharge. Less than 10 hours on standby to discharge. Lenovo suggested a factory reset (ha ha) to fix the problem. I'll humour them for the weekend.
Heys guys, this is my second week with my nexus 7, I'm loving it but I have "weird" battery drains while sleeping with wifi on.
I say "weird" with quotes because I believe this would be a normal behavior, but I have an iPad (I know, it's annoying comparing devices) and it lasts more than a month with a charge even with wifi on and receiving notifications.
That battery life is impressive, I know it has a giant battery and all. :silly:
I think nexus 7 regular-use life is amazing, I just find this idle drain "weird".
My main question is: what's the average nexus 7 battery drain with wifi on per hour while sleeping/idle? or a more real-world scenario: how much % do we lose overnight with wifi on?
Yes wifi while sleeping DO seem to drain a lot for me too, before i changed it to off in sleep state i had to charge at least once a day, sometimes 2, close to making the nexus 7 a very disappointing device, i also got used to ipad's long lasting battery
anyway i can live with wifi being off while the nexus is in standby and the battery life that way is amazing compared..
of course other things is worth turning off too, to safe battery life, like no live wallpaper, no location service and so on.

4.2 has definately had a negative impact on my batter, bar non !
I used to get 3 + days of normal useage(normal for me), but after 4.2 it dropped by a WHOLE DAY to only 2.
I have switched it to disable wifi when sleeping, like you... which helped gain about 22hours of battery life, taking it back to about 2 days 22 hours, but thats STILL worse than 4.1.1 with less things turned on?
Also, how can I stop Wake Locks I don't understand them but theres absolutely no need for my tablet to be doing things whilst I'm not using it?

I disagree...
if wifi is off, at least for me, when I turn it on it doesnt receive the old notifications...
if I leave wifi on while sleeping, when I turn n7 on all notifications are there... that's why I need/want to leave it on

Fair enough, but for me I would much rather the tablet do as I've told it and disable WiFi whilst not in use.
Instead it decides to do this, but then keeps causing wake-locks, so the deep sleep is never activated at therefor battery drains...
I've lost literally a day use time between each charge which is every 3 days
times that by 3, you have 3 extra days charging in 9 days, times that by the year and your up to 3 weeks extra charging a year, justify that?

great point of view, in this case maybe its not worth it, but that was the point of starting this topic.
As iPad drains almost zero battery while sleeping, I was hoping nexus/android could do the same, then it would make sense keeping wifi on while sleeping.
Since this seems impossible, maybe it's time to let it sleep peacefully :laugh:
At least battery life in regular use is great for such a "tiny" tablet. Overall I'm very happy with it :good:
Hello
Anybody here bought the Leapbook can give me a review about the battery?
I bought Innjoo leapbook A100 32 days ago, and it performed very good,
However starting from 15 days ago, it is turning off suddenly when I’m using it.
I think it is a battery problem; I observed and noticed, at first it did so when the battery is at 45% or less, probably after 7 hours internet usage. Now it do the same after 4 hours usage and the battery is charged 70%
In the leapbook description it is written that the battery should work 10 hours normal usage, so why it is acting like this when the laptop is 32 days old only? It is still brand new. The battery is becoming worse and worse in a short period.
Beside that, I noticed a red dead pixel in the right side of my screen, which indicates low quality screen was used in that device.
I don't recommend this device for anyone...
Please share your reviews.
Thanks
Hello,
my uncle just bought me a brand new genuine Redmi note 7, I opened the box and turned the phone on.. I noticed that the battery was at 66%, I set up the phone which took a minute or less and that's when I was about to connect it to my wifi BUT then I notice that the battery is 63% ALREADY.. Now knowing that the phone has a 4000mah battery I was beyond shocked too see a 3% drain with low brightness and just 1 minute of light use literally no SIM or internet was being used.. so I turned it off and charged it to the max.. After that I turned the phone back on to update miui.. I connected the phone to my wifi and started updating to the last version.. available from the updater.. it took less than 10 minutes.. and guess what I see? 100% to 89% in less than 10 minutes that's crazy.. I bought this phone because of this guy w ww. youtube. com/watch?v=3gaWbx2x06s as we can see in the video he gets almost 8 hours of SOT with full brightness wifi and youtube FHD... right now I'm doing the same experiment and adding battery saver setting and my battery is draining fast I'd be surprised if I got 4 hours of sot... I don't understand... what's wrong? The phone is new and genuine since I verified the imei.. Thank you.

I believe every phone does the same thing like that when you configure them for the very first time. Full brightness, wifi scanning, mobile data ON, GPS ON, sync ON for a few minutes can consume lots of battery.
My advice is to fully set up your phone with all the apps you want and turn off any features you don't use. Use and recharge your phone normally for a few days. Check for battery consumption stats using native graphs or popular battery tracking apps. Analyze graphs and stats and draw the conclusions yourself. (Don't trust everything people say on YouTube, trust your own experience.)
In the worst scenario, you can always return your phone within 7 days of purchase. I hope you don't have to! :fingers-crossed:
My brand new redmi note 7 is a little fast draining right now too which is a little disappointing but my redmi note 5 was also the same fast draining when I first purchased it and it improved so I really hope this redmi note 7 does the same and improves.
I have both phones side by side right now so I can kind of compare usage

Yeah even my mediatek redmi note 4 didn't drain like this.. now when it gets to 15% it just discharges completely.
One thing I will mention is facial recognition. It could possibly drain the battery faster so I have just turned it off for testing purposes. I need to see what difference it makes but that's really the only difference between my two redmi phones 5 & 7.
Any new phone battery will take a few charge/drain cycles until it is calibrated correctly.
Use it for a while and see if the battery settles down.
Also different countries have different mobile systems. This will also affect battery life as the phone needs to continually scan for a signal....

I know the post is old but I have the same problem ... I think we are so many to have it !!
I have a Note 7 for more than a month and it never went well ... I managed to do only 3 days but almost without using it, there are people who also do 4 or 5 days of use ...
Anyway if I use it it makes me amalapena 1 day ...
When I use the phone I see that it consumes my battery quickly even if I just navigate the phone menu.
I've already done at least 4 reset but it didn't help
I do not know what to do..
Did you solve the problem?
miui 11 could help?
Thanks
Imposible to do 4-5 days with this phone or any phone when u use it. Why do u have smartphone when u dont use it and u care about battery?
What version MIUI are you all using?
I'm still on 10.3.5 and battery life is great.
I average 9.5 hours SOT ( 2 days worth) with normal use and have got as high as just under 11 hours SOT a few times.
If you're not on 10.3.5, can you roll back?
I've heard of battery life issues after updating to the newer versions which is why I'm staying on this one until they work out the kinks
My battery life has improved since my earlier post just as I expected it to The note 5 does last a little longer when I put them side by side but they are both great phones and the batteries last for ages with normal daily use!
I barely use 50% with gaming (currently clash royale) social medias, spotify for around 2 hours and some other stuff plus I'm working 5 days a week so I don't get to see my phone for most of the day anyway

might be a dumb question but, how/when do you charge your phone ? do you wait for the battery to reach 0-10% and charge it back to 100%? or you do the 20% to 80% charge "cycle" ?
I try to charge my phones every night now when I go to bed, The note 5 & 7 are around 50% most days from useage and I charge them from around 8/9pm until I wake for work at 5am (Living the dream)

and what SOT do you get with the 50% usage ?
I am not sure, Because it almost never drops below 50% in a days usage I have stopped looking and worrying about battery life It just lasts and lasts for me.
However I will try and take notice over the next few days and report back if there is anything to report...
