Maybe I'm being dense here so forgive me. But if Chrome is proving such a battery drain surely just use an alternative browser until Google fix it?

Yes sorry I did try other browsers so it seems browsing per se causes the drain, maybe Lollipop itself is the issue.


The problem is the configuration of the cpu governer. It ramps up to high speeds far too quickly in response to very light loads. It also throttle up to 1.5ghz in response to simple touch inputs. That is the reason you see such huge useage while browsing as you are constantly scrolling and reading, all the time using the touch screen. The governor won't allow the cpu to throttle back after the touch input finishes and it just sits there. Your graph shows it perfectly, even when cpu load drops to about 15-25% the cpu speed stays at a pretty consistent 1.5ghz level the whole time.
People reporting good battery life appear to be mainly using it for watching video where there is little to no input for hours at a time leaving the cpu sitting in its lowest power state while the decoding is handled on another part of the soc.

We are not going to see an improvement without major configuration changes to the base kernel as it controls all of the cpu power scheduling and there has been no changes in any of the ota updates.

Thing is for me there are no real alternatives.



I love most aspects of it but the poor battery life when browsing is hugely disappointing, you happy with battery life?

Poor battery life is due to chrome. Even macbook pro's suffer battery life issues on chrome

so far so good. i am dissapointed that there is no damm cover for it though

For me browsing with other browsers causes drain too, 5 hours SOT for me is v poor, I`ve initiated the RMA but would ultimately like to own this tablet, just the issues and the price dropping is a concern.

Surely that can't be true otherwise how the hell could that get through testing?

u would think, BUT I can assure you the L build was even worse than the Q which I have atm, it wasn't uncommon for it to lag for 5-6-7 seconds. Apparently there is an R build out yesterday too, the fact they are releasing builds so quickly surely is significant.

Its a real pity as there is lots to like about this device.
 
Think I'm glad I didn't pull the trigger on this straight away, bit of a disappointment :(

The price I could have justify if it was a solid device but the build quality not being up to HTC's usual standards and the software issues are a massive shame.

I might still get one if the price drops as it will be 99% used for couch browsing.
 
Flashed to R build earlier, I'm seeing significantly better battery performance, instead of heading for 5 hours SOT if browsing its now looking more like 8 and a half, hmmm.

You put the OTA on? I went too the R last night, still not happy with battery so far.
 
I'm surprised no ones mentioned this but this is my third Nexus tablet (previous had Nexus 10 and Nexus 7 2013) and yet for the third time in a row, I'm suffering from edge light bleeding again!

This one is the worse one I've come across but I don't know if I can return it or if I can be bothered as my friend bought it from me direct from Google Play, Hong Kong.

What disappoints me most is that this is meant to be a premium nexus tablet and they cant even get the edge light bleeding right!!
 
Mine got shipped back off today, I'm not willing to give them any more time to fix what "could" be software issues.

Plus the dimple got worse on the back where the heat was.

Shame as I really did like the device, and wanted to keep it, but £400 I expect better.

You can always buy one if things resolve, and at a cheaper price most likely. I received my return packaging today too, no instructions on procedure included either, even now I'm undecided as browsing time is def longer .

I thought mine seemed to be a bit better browsing wise this morning, but I didn't want to take the risk, given short timeframe to return etc. And as you say, can always pick up another 1 in a few months. Next one won't be black though, finger magnet lol.
