Re: Yoga Tab 3 Pro 4300 MAH battery!?!

I bought YOGA BOOK Android two months ago.

I had a same problem.

 

The Apps, AccuBattery, Battery Doctor, Power Battery told me that

the YOGA BOOK Android had 4,300 mAh,

but the specification said that it had 8,600mAh.

 

So I did go to Service Center in Korea

and the service center engineer told me they couldn't cofirm whether it was OK or NOT

before he dissassembed it.

 

I didn't want to disassemble new device,

so I came back with nothing.

 

After this,

I don't want to keep this device,

so I sold it out as second-hand device with discount. T.T

 

I hope this can be helpful.

Re: Yoga Tab 3 Pro 4300 MAH battery!?!

No news. The battery now says it's around 3450 MAH which makss it seem like this tablet has a dying battery. I cannot replace the parts either because I bought it from another country. All in all, Lenovo is a scam. Awful company, and I deeply regret buying this tablet. However I am stuck with it. All I have to do is hope that the battery does not fail much more than it already has, otherwise I will have paid $900 CAD for a paperweight.  My battery at this point lasts maybe 6 hours.

Re: Yoga Tab 3 Pro 4300 MAH battery!?!

I have new 4 GB version with preinstaled android 6.0.1.

Original version was YT3-X90L_USR_S200028_1609230146_WW17_BP_ROW. It worked perfect.

After OTA update to version YT3-X90L_USR_S200219_1703231241_WW17_BP_ROW battery life

is horrible. I tried to factory reset, it did no help.

Battery drain is 15 % overnight in airplain mode.

 

However root is not avaliable for this version. Without this is not possible detect more detailed informations what

reason to battery drain.

 

I think that tablet has 2 batteries, main small battery in think body, bigger in tubular part. Maybe after update is second battery can not be used. Battery applications displaying only main battery.

 

I don't now, in my case something is wrong.

Re: Yoga Tab 3 Pro 4300 MAH battery!?!

Sure seems like the second battery doesn't get used. It doesnt get warm during charge or discharge up there in the grip at all. That and I've measured three of these tabs using a hardware ammeter and got between 3900 and 4100 mAH put into them.

 

I Love the design of the tablet but 5-7 hours is dismal @ 10% brightness, 2 hours projecting a streaming movie is not a useful feature. To say I am disappointed is an understatement.

Re: Yoga Tab 3 Pro 4300 MAH battery!?!

 

This is all I can get into a full charge from dead. Tested 3 tabs from one retailer. Not close to 10200 maH, I brought it up before but my account was deleted... Charge rate * hours yields similar numbers without ammeter. Charge rate drops as resistance increases in battery with charge level.

 

Obviously it isn't so simple, but I'm pretty sure if I have cells totalling 10200 maH capacity, I should be able to put somewhere near that much current into them. None of these have allowed that. They top off well below where they should.

 

These numbers support my poor run times, being ~5 hours, 2-3 hours in some cases, dismal if I project... As it stands I love the design, hate the battery life, my 4 year old GTP still lasts longer.

 

I'm curious if anyone else has tested similarly?

Re: Yoga Tab 3 Pro 4300 MAH battery!?!

My Tab 3 Pro has the exactly similar poor battery time after the most recent security update (april 2017). Were any of you able to solve this issue?

Will Lenovo listen to this important complaint? Not being able to use 60% of the total battery capacity sounds like the worst nightmare to me (for their premium tablets more so).

I think they can fix it with a software update. Has anyone been successful in getting Lenovo to do something of this level of criticial importance?
