Sprint 2.1 Update issues

I upgraded to the Sprint stock 2.1 update a few days ago. My battery sucks ass, and the whole thing is just slow. My battery lasts maybe 1/2 to 3/4 of a day and anytime I make or take a call or msg/email, the phone freezes for a few seconds at a time.
I've looked on here for answers, but it's all scattered and I can't find much that directly addresses it.
Any and all help would be useful. I'm sure rooting and trying something better would be better, but the stock working without issues would be nice. Thanks.

Rooting is out of the question for you since you upgraded stock 2.1 As far as the battery is concerned you should be able to access your battery stats in Settings>About phone> Battery > Battery use. Of course, you should check the battery use after a days use, so basically charge it to full and let it run down then check the stats on the battery and find out what is using it.
The post the results here and we can assist you further.

I think you will see the google maps issue. I looked and found that it was using 91%. I wish I could adb and pull it out...lol
btw I was quite aware of the impact installing the update.

dont worry, the 2.1 stock rom is like a red headed step child, eventually its going to get beaten so dont worry you will be Adb'ing tons of stuff out in the future lol.

So any reasons as to why it runs slow. Is anyone else having this problem?

I have stock/official 2.1 on mine....and mine works faster actually...my messaging client is wicked fast than in 1.5 .....browsing is faster too...overall the lag level is gone down for me.....
Oh and reg battery...I improved my battery by disabling "always on mobile network connection"...that helped the battery a lil bit...
I easily get a day out of my battery...
You should try to reflash and see if it gets better..

Ditto, I dont know if Im a big fan of this update ..

WOW, i have the leaked 2.1 from fresh on my hero and i have no lag and great battery life. Try another radio as i found the new stock one to be pretty bad.

I updated my girlfriend's Hero to 2.1 a few days ago, and she has been less than thrilled with how it is performing and wishes she could go back to 1.5.
She says the battery seems to drain faster, and she has been having issues with the browser (having trouble selecting text boxes because it takes two taps now due to zoom in, regular freeze ups). The messaging icon also keeps reporting that she has one message, only for her to click on it and have nothing.
One thing that hopefully will help though was turning off Latitude. She was just nosing around in Maps one day and activated it but couldn't find where to kill it. Google awkwardly buried the setting to turn it off completely under the "privacy" menu (the forth option).
What's bad is that I tried to save her the trouble of dealing with ROMs and roots and spared her Hero from my experimenting, but so far the official 2.1 seems to have as many issues as a buggy ROM would. It's very frustrating.

Performance Improvements with 2.3.4

Hey guys,
Do you notice the performance improvements with the new 2.3.4 update? I have noticed that the screen responsiveness has improved significantly, especially in the browser and in the official Facebook app.

I agree, the screen sensitivity is better while using the browser and when typing on the keyboard. So far that is the only difference that I've noticed. I'll give navigation a whirl this afternoon.

I have just recently updated so have not notice much difference. Maybe I will keep looking at it longer to see.

Don't see any difference here.

Initially I thought I observed some perceptible improvement in scrolling smoothness and touch responsiveness, but at this point I can't honestly say it's not just placebo effect from the update.

For the Nexus One user, the only real "improvement" 'till now is to lose root. I've just received GRJ22 OTA a couple of minutes ago, and i'm going to "hope" that, at least, battery life will show some kind of improvement.
Of course, i also have faith on XDA's guys to find a new way to have root on this one

Battery life has increased by atleast 15% + more responsive.

Battery life still sucks.
There is already a root for it. Just flash the su zip file. Not hard.

My battery battery life is much better now. Currently at 36% after 24 hours. Normally I got around 18 hours.
But maybe my usage has been somewhat lighter because I have been busy.
Stock 2.3.4 and no root.

I never had the battery issue on 2.3.3 and Gingerbread actually brought me a with MUCH better battery life than Froyo, no further change in that on 2.3.4.
After a day on 2.3.4, it seems a tad bit faster than 2.3.3 and the BACK button seems to be working properly again. Previously, it took multiple taps in order for the phone to register a click and I'm pleased it's finally fixed in 2.3.4. Also, the 'black screen' bug seems to have gone but I need further testing. I'm pretty pleased with the update so far.

mine is running definitely smoother - before it would stutter after a few hours of use - I would have to reboot the phone to clear up the glitches
so far so good - I'm happy!

Same here, running stock 2.3.4, the update has fixed the black screen glitches and the 2 second delay issues. I feel its quite stable now, and the battery life has also improved marginally.

Battery life has improved so much since I flashed 2.3.4! Used it as normal today and I still have 50% left
Sent from my Nexus One using Tapatalk

7 hours 5 minutes on battery, down to 64%. Minimal use.
At least I should beat my 11 hour time yesterday. Something was boned up yesterday, today it is seeming better.

Really appreciate the feedback regarding battery life. Can anyone put up a bit more info with the N1 setting (wifi sleep policy, screen auto brightness, etc).
I'm still sceptical with this battery improvement after being 'traumatised' with bad battery life upon upgrading to 2.3.3 compared to 2.2.2. 2.3.3 can't even last 1/2 day compared to easily getting full day with Froyo 2.2.2 with my usage pattern.
I'll stick to 2.2.2 at the moment until clearer information available. I'm not going through the hassle of downgrading from Gingerbread to Froyo again.
Thank

Sure about that?
So far i have only read, that this bug still exists. Also the issue report on the google mobile page hasn't been marked as solved by a google employee.
btw, I'm still on 2.3.3

Battery life is at 50% after exactly 9hrs with phone idling most of the day except for maybe a combined 20-30mins of web browsing earlier. Doesn't seem great, maybe better than before? I've had Wifi Sleep on Never, although I have been at work with no Wifi to connect to.

Feels smoother and the battery life has improved some so far. But, I did not have battery issues with 2.3.3

50% for 9h of mostly idling? Not that good compared to Froyo 2.2.2. My N1 running Froyo 2.2.2 only consume 20%-25% for 9h.

MX battery life?

Hi! I got my MX couple of months ago, and I can tell I love it. Anyways the only things I wasnt happy with were the battery life and reception, and so I updated my phone's flyme os yesterday. (from 1.0.3 to 1.1.1)
I assumed the update would fix the issues ( as I think it did for the reception ) but the battery seems to be even more horrible after the update.
It seems that after the update my MX didnt even completely charge up. I put my phone on the charger at around 2:30 and unplugged it at 13:30, so it was on power for about 11 hours, but it didnt even charge itself completely in addition to the fact that it stopped actually charging at around 8 o clock as we can clearly see from the "today" screenshot.
Then comparing it to the "yesterday" screenshot with 1.0.3 we can tell it charged itself up completely.
Ive got the new 2core model with the updated 1700 mah battery (which should have the best battery life of all of the mx models) and this makes me wonder what is the battery like on the other mx's if this is normal. And yes my phone was showing the charging animation on the screen during the time I mentioned earlier in the message.

Thanks for the tip, I'll try this right away. Flyme will backup all data, right?

Except apps. If you have it enabled.

1.0.3 here, quad core model, my battery is fine, gets me over a day with normal use.
However I admit that it could be better.
Its also well known that 1.1.1 contained a bug that ate battery, so stay away from that firmware.
I didn't test 1.1.3 yet.

My MX arrives this week and I'll be measuring the battery carefully to see if I can't find a replacement. (Yes, I realize it's not supposed to be "user replaceable", but the teardowns confirm that it is if you've got the patience and dedication. Here's hoping there is a higher-capacity battery in the same form factor.) Apps are nice, but more juice is better.

1.1.5 is out, do you think I should try that? Theres no thing mentioned about battery in the changelog but there's some magic in updates sometimes, isn't there?

Hehe that's true. I use 1.1.5 and it feels pretty good.

1.1.5 is nice, however there is a bug in android terminal emulator.
The osk wont work until you change the input type setting to word based.
I also suggest prerooting the image, Ubuntu works nicely on it too.

Yeah I heard about that bug, but that's an easy fix isn't that Also never ran into the need of terminal on my MX.
There was someone on meizume forums telling he could upload a prerooted image of 1.1.5, and as I have 0 experience on how to preroot the file I wish he could do that. You see I'm a newbie - don't just tell me to do things, please tell me HOW to do the things aswell ^^,

Kedros uploaded one already. You can just fetch his.

Battery is 71mm x 35mm x Unknown Depth. If I can find a few batteries matching the length-width, I can start trying to transplant them into my MX quad core.

Please keep us updated on that.
I would love to stick a higher capacity battery in there.

OTA Update 2.4.1

OTA update has come 2.4.1 nd i am very happy that they are giving updates and solving the issues nd bugs..but... nvidia will give any android update ever or we are now stuck on 4.4.2! ?

Nvidia has stated in a e-mail that we will get 4.4.3 so don't worry

Android L is still in development and we haven't had 4.4.3 or even 4.4.4 so lets give Nvidia some time!

I'm glad That Nvidia is putting out all these updates. I really really want the battery fix thoug, hopefully that update comes fast.

Well what is the problem with battery ?? Im having no problem with it. It gived me 15 to 20 hours of battery life in battery saving mode with normal use no games .

I really hope we have a shot with Android L. I just bought this tablet, and seeing the Moto G will get the update suggests that 1GB of RAM should be sufficient to run the new OS.

The problem is I always end up having to charge it after about two to three hours of use, in balanced mode, most of the time just watching Youtube videos. I am almost certain that they advertised much more battery life. The other problem I have is the meter in the notification menu just stops working randomly and I have to restart the tablet to fix it. maybe a defect in my system alone, but annoying nonetheless.

To me its sounding like you have a defective unit mate.

I posted in a few places there is definitely a battery issue I only got about 4 hours playing a game and sending some mails. for a 4100mah it seems less or is it about right? the screen brightness was at 30%, gangstar vegas total play time was about 2hrs 40min and the rest was email on the native email app. balanced mode.

Glad to hear that helped, I'll try when mine is (hopefully) returned after touch screen issues. I was considering installing juice defender app, which works wonders for extending my phone battery life, but will try power saving mode first.

Extremely Disappointed with K1

I jumped in and bought a K1 to replace my dying GPad GPE. After 3 days, this seems like a huge mistake.
The K1 is very laggy in basic apps like Play Store and Chrome, does not register touches very well and has terrible battery life. I even charged it overnight and didn't get a full charge. On top of that, I am constantly getting the screen overlay message any time I need to enable a permission.
What could be causing this? This tablet is so highly regarded I don't get it.

For charging you need a 2 or 2,5 A charger. Then it will charge (if it's not faulty) in around 2 hours. The screen overlay message is coming from the quick launcher (or how it is called). So disable it or give it the right to draw over other apps.
I don't have problems with lags or touches. Are you on the latest updates?

I am using the correct rated charger. This even happened when charging with the tablet off.
I am on the latest update. I waited to install my apps until after all updates were applied. The touch issues may be lag related. The back button almost always requires multiple touches. Keyboards often time register multiple touches or just freezes.
I am also noticing network issues. Apps report loss of connection when the wifi shows connected.
I hate to say it, but I am leaning towards returning this for a Samsung.

Also a recent owner of the k1. Running stock firmware (1.5) but with BitO-K kernel. The only thing I am experiencing is mediocre battery life, charges from 50-100% in under an hour using a 2.5A charger. The only thing that sucks, and this goes for android tablets in general, is the removal from 4.4 of the TabletUI. Seeing we're already at 7.1 and TabletUI is still dead, it looks like we'll have to fight to get it back again.

That lag is not normal. And my tablet charges from around 10% to full in about 2 hours. Maybe you should try a factory reset. If that doesn't help I would return it.
I won't buy a Samsung tablet. I would try a replacement. I own the k1 for a year now and I'm still very satisfied with. And Nvidia updates it. Which Samsung usually doesn't.
Don't listen to Nvidia trolls... ⬆

Your experience does not sound typical. Perhaps it's a hardware issue, but I agree with @edisso10018 that the first step would be a factory reset.
Wish you luck!

The Nvidia CPU is pretty good shame it's not the X1, It performs better then some of my phones with QC chips, Do a factory reset and see if the lag is still there, Battery life is poor can agree on that

My k1 is over a year old it is still playing games with no trouble yes a agree with the battery life but mine charges with no problems a have noticed a little slow down but am not running bit os updated kernel yet but a still rate 10/10 best tablet a ever owned.

Tablet is laggy, no denying it.

K1 here-- I don't run stock (DU 6.0.1), but I used BitOK for a while and realized its not very good. Switched back to stock kernel (from my ROM) and its more stable. You don't lose out on much anyway-- BitOK doesn't have features I want like voltage control. Examples of instability caued by BitOK: GPU was stuck at ~350mhz, would not ramp down fully to 72mhz. Also stock is smoother. You can still use adiutor to monitor and control a few things.
One more thing: be very careful when flashing blobs and other stuff in fastboot that it is for the K1 version and not OG shield! A lot of devs posting these things arent explicit as to which version. DTBs and Blobs are specific to the shield type-- one might work for the wrong tablet version, or it might brick it, or it might be unstable.
As for the Batery life I can tell you it does suck even on the best case scenario. There is no way around this as it is small and the large screen, as nice as it is, sucks a lot of juice. Lowering brightness helps somewhat but still I'll be lucky to get a couple hours of SOT out of it.
For the price its a great tablet, with a few small compromises, such as bat life, but thats the price you pay for great screen and sound at a cheap price. We are lucky to have at least a few devs still doing work with this device, and luckier still that nvidia is STILL supporting it with updates, even if slowly. They recently announced 7.1.1 will be forthcoming.

Mine was laggy too, I flashed stock firmware with my PC and now it's working perfectly.

Bought mine as a refurb and it works fine. I think you either have bad hardware, or a bad install. Try flashing stock and see if it improves.

Tbh my only complaint is with battery life, I switched to BitO to see if it got any better, the tablet is smoother with this kernel than stock but the battery is the same, I wish we had UV'ing, my favorite setting on any kernel, back on my N10 my battery could easily be improved 10-15% and the heat was reduced drastically, good binned ones could shave up to 200mV on some steps. K wish this was implemented

I just bought a K1 (discount price 169€) and I don't have this problem at all. Even if I use only 1 core (settings performance) for basic app it's smooth smooth smooth.
And the battery life is huge !!
For gaming tho I switch back ofc the performance setting.
:good:

I bought a K1 three weeks ago to use as a display for my phantom 4 quadcopter. I am very impressed with its performance. I'm not experiencing any lag other than at startup. Once it's up and startup is finalized I dont have any problems. The battery life isn't great, I'll agree there but hopefully it gets better with Nougat.

I bought a K1 last week to replace my aging Nexus 7, did a factory reset and still wasn't satisfied with it being laggy. Did my share of Google searching and finally stumbled upon a quick fix to try : disable Daydream. Since changing this one setting it has been very smooth since, no issue for lag or touch registrations.
Give it a try, might not help your charging but I did notice a much reduced battery drain while sleeping also.
My only other changes were to root, change the DPI to 240 and use the Google Now Launcher which compliments the display nicely.

I wasn't happy with it as well until I flashed cyanogenmod 13 and a custom kernel with overclock. Now it's a beast, battery is great, signal as well. And I also now have the option to OC the processor to 2.5 GHz before I play some more demanding games and then set it back to 2.2 or even lower if I won't need all the juice. Seriously, the stock marshmallow ROM sucks, I have only heard bad stuff about it. Also, the nougat update is about to come out so I'd give android N a chance, too.

About the battery life -- see which apps are using the most juice under settings/battery/. Some of them may be using more CPU cores, and have a higher frame rate than is needed. Go to settings/App optimisation/ and crank the numbers down. Next go to settings/Accounts and see the long list of things that want to autosync with you. Turn the autosync off for those you aren't using. Turning off wifi except when I am using it has made a significant difference for me as well.

Putting the CPU at 80 or 90% CPU speed in the performance settings will get you that reduced power consumption. You might not even notice the speed difference. These speed tiers also run at lower voltage.
Using the GPU frame rate limiter will dramatically extend gaming time too. I find 30 fps acceptable most of the time.
Of course it would be nice to run the thing unrestricted, but it's just not practical when you also want battery life. Look at what Nintendo is doing with the clock speeds of the X1 in the Switch.
