Phone gets slow when under 30% ZTE Axon 7 Help - ZTE Axon 7 Questions & Answers

Hi there, I've owned a Axon 7 for 8months now and I can't remember how it used to be battery wise at the start but for the past months now when it drops to 30 or 25% battery the phone get really laggy and is super annoying. Is there a fix to this? Thanks

Check the settings in Power Manager. Might be set to reduce performance too much when low on juice. Probably got it on auto ultra mode too.

Have you fixed your problem? I have the same question, so I want to know......

Phone shuts down its 2 High Performance cores, 2 little Low Power ones only work then. IDK why, maybe something in ZTE's power managment, ez fix just go to performance mode

How to tell if battery is defective?

I am within the return period of my G2, but not sure if my battery life is normal or not? I get 3-4 hours screen time on VZW 4G, with sync on and all GPS and NFC related stuff off, running a de-bloated LG rom. All the reviews I have read they getting 6-8 hours of screen time, pretty much twice of what I am getting. Is this normal or do I have a defective devices? I kind of don't want to return as I have a screen protector I got at the same time I got the G2 and hat the store install so that makes transferring the protector harder? If it really is defected, then I must return it, but how can one tell if battery is really defective or actually normal?
On a side note I know people with Galaxy S4 getting similar battery life as me, but I would think that would be expected since the S4 has a smaller battery vs the G2. Thanks.

Depends on many things and mainly what brightness level u get the screen time u mentioned for. It is normal to get way less screen time with 100% brightness than say with 50% or less brightness. Also u don't mention where u get the said screen time. Is it browsing the net or watching youtube vids for example or playing heavy 3d games? That affects screen time as well. Way too little info u shared here for anyone to be able to really help you...
Try disabling sync, Google now, and have it on 50% auto brightness...it has helped me a lot.

The OP has a point. I have seen that the Android System takes almost the half of the battery stamina. And after tracking what exactly it came up that the Radio drains to much battery. I try to find solution or anything but didn't find anything yet.....

I used wakelock detector. The app showed me that the most power is gone to the radio.
I can't understand a sh*t. Everything was fine and suddenly it starts to consume power like hell. I disabled play services and all apps except play store. Removed unused apps even those from LG like dictionary etc. Now i am at 87% with 1hr 14min screen time and android system is still with biggest rate of power consume. At least android os is no more second power consumer....... i am goin nuts right now....
Even my SXL after all updates with everything on has less power drain then the G2...and the most consume comes from the screen.
I disabled knock on and I am at 85% with 1h 8 min sot. Android OS is the second highest drain but android system has settled down a bit.

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.

Okay, I don't think its a defective unit because I tried using it on power saving mode all day today with music and reading and its still above the 70% mark. I think the bug is that the balanced setting drains a lot of battery.

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.

Anyone returning the ZF2?

I was wondering if anyone is returning their phone after getting the US version, and having some issues with it, im thinking of sending it back to NewEgg.

Whats the solution to battery life and overheating during regular use (not on the charger)?
You realize your issues with heat build during charging are because of the fast-charge technology, right? Totally normal, as a ton of power is flowing into the phone. You can always use a slow charger to charge the phone while in use. You shouldn't have any heat build up during use when not also charging. I know I don't. The hottest the phone gets is slightly warm.

For overheating, use a different adapter if you have the 1.8 GHz version. Battery life, just get a third party battery saver and turn on airplane mode. That will save you a ton of battery. I did it for mine and the phone last from 6 A.M to 10 P.M.

Very dependent on ambient temperatures as well.
Anandtech has confirmed that the panel in the ZF2 is inefficient compared to competitors, so not much can be done about that aspect. Their analysis of the phone is in depth, as are their other reviews.
I would like to return mine because the battery is performing right under the Optimus G I owned. With 3000mAh I was looking forward to battery comparable to the G2. If the next OTA improves battery, then I'll keep the Asus.
"I'd Totally Hug You, If That Was Something I Did"
Dang, so the bad battery is a hardware related (screen tech) issue based on that review.

Yeah. The people from Anandtech are pretty good at evaluating devices. Also this would explain why the battery drains rapidly during use & barely when inactive. Battery life is very important to me, so a phone with a removable battery might be best.

One thing to keep in mind, is that though the display uses a lot of power, the Intel chip itself seems very efficient. Not only does it sleep well, but as is shown in the PCMark testing on the Anand website, it uses its power very efficiently. Thus, though the phone's maximum display on time is much lower than the other phones, its practical usage time is fairly similar. I get around 5 hours screen on time with 1-2 days of sleep time.

For me getting even 4hrs is requiring me to disable apps, use greenify to kill background apps, and use min brightness. I tried factory resets, so doing those over and over isn't improving my battery. Honestly I just want a new phone with the battery life of my G2, since development is slowing down for it.

Now hold on guys. Even if this phone has some battery issues, we can all still say that this phone is very acceptable. Right?

Besides battery I don't have any performance complaints. This is the main aspect I complain about. I'm still impressed that mine rarely warms up, signal is better than my G2, the battery cover has the brushed look like my Asus laptop, and so on.

Is a high battery usage when screen is on (1%/minute) normal?

Hello,
I am using a Note 3 since yesterday and I noticed a very weird battery usage pattern.
When the screen is on it consumes about 1%/minutes, which looks crazy high to me. On the opposite, when the screen is off it consumes close to nothing.
Is this normal?
I'm running a stock Android 5.0, I factory reset it yesterday and I don't have any power hungry services running in the background.
The phone has not been used for a few months I don't know if that could be the cause of the issue.
It is very normal if 3g or Wi-Fi is on and play games on high brightness.
I am on 3G/WiFi, but I'm not doing anything computationally intensive. I'm mostly reading email, using WhatsApp. I'm not even watching videos.
Brightness is set on 3 out of 10 with automatic regulation so I'd not think it's it.

That was what I suspected. I think I'm going to order a new battery and see if that helps.
Yep, weakened battery. 1% per minute, while you are just reading emails and stuffs means 100 minutes, that is simply not possible, Note 3 with a fresh battery should output at least 3-3.5 hours of Screen On Time, and a little more if on WiFi.

I'm on Wi-Fi. 7-8hour using, 3.5-4hour Screen On Time. With Clash of Clans 1-2hour Screen-On-Time. Gaming Clash of Clans (drains battery more than all other 3D games). Is this normal? I not sure, other Note3 Snapdragon users also run battery with 8hour with 3hour Sreen-On-Time. Maybe my battery bad? Or good?
Thanks!

Update to Latest official firmware and not use Root if no necessary. Battery is good without Root and latest Stock. 2% per 5minute with Wi-Fi in Internet browsing. I think this is good

Well gaming certainly drains significantly more battery than normal usage, that's for sure, but I honestly have no idea about that game and how much CPU and GPU intensive it is, but if its a demanding game then I would say its normal.

Before you start buying new batteries, I think you should check your phones wake locks.
This method added significant battery life to my SM-N900P. Go to settings/device/sounds and notifications/other sounds and disable Screen Lock Sound, Touch Sounds, and Haptic Feedback. Or just disable everything in that section (which I did)

None of those are active. Also, wake-locks should affect mostly the battery drain when I'm not using the phone (they keep it active). How do they relate to my problem?
i have this problem too!
if turn off power saving its going to die
i try others rom like Pheronsis Rom V.x ... Aurora Rom and many other but those have bad battry drain worse than stock Samy lollipop.
and now on dark lord rom its better and battry using like stock rom.
however i have battry drain!

You can try to track down what's consuming your battery using an app that gives you more insight that the system one. I am trying GSam battery monitor and I think it's quite good.
By the way, it reports that my phone is getting [email protected] I'd like to compare this data with someone else. Also, it reports that the processes taking most of the power are Android System and the kernel, which should mean that I don't have any process eating up too much battery

Tab S2 8.0 keeps rebooting.

Hi all. I bought a tab s2 for my step-dad this past Christmas and it keep rebooting once reach like 15-20% battery. One point, it got stuck on Samsung logo. I had to hard reset. I ended up exchanging that tablet with Amazon. Now the exchange tablet is doing the exact same thing. What are the odds of this happening again? Do these suffer from random reboots? I don't want to exchange again and it happens for a third time.
The tablet went to 0% charge. And it didn't turn on since then. It's currently on Samsung logo. I have older samsung tablets. And this never happens.

Wth is going on with this tablet. I finally got it replaced by Samsung. New one is doing the exact same thing. Tablet is been used lightly. The tablet died to 0%. Now it doesn't want to turn on again. Crap is annoying.
Going to restore and install one app at a time and see if maybe it's an app that causing it. It has to be.
I have the same issue with S2 9.7". It randomly reboots with more chance the lower the battery is. Mostly zero chance above 50% then with around under 30% it happens way more often, especially when you install/update apps. So I guess the entire Tab S2 line has a battery issue, maybe a too low voltage over time, resulting in CPU/flash memory becoming instable of too low voltage. Mine was actually just 2 weeks old after showing the issue. Instead of swapping the battery, the repair service mostly will just swap the motherboard, which will not solve this issue.
Thought I had a fix - but I just got a reboot
Hey everyone. Just wanted to tell you i got the exact same problem in my T713. It's most certainly a spike on battery usage and the inability of the battery to keep up due to degradation, as this problem presents when I'm trying to do intensive tasks like watching videos on youtube or entering many apps in a short timespan.
My personal fix was to underclock the CPU maximum frequency using smartpack from 1804Mhz down to 1612Mhz. Obviously you need to root your device for this fix. Once i did this the rate of random reboots diminished substantially while minimally impacting performance. I know its not a perfect solution, but if you use your tablets just lightly, this might certainly work. Changing the CPU governor to some conservative mode might also do.
Hope this helps everyone.

Seems to work for me too on my T719. For the first time in ages I was able to use my tablet until it shut down itself because the battery was too low, usually it started rebooting at 35-40% of battery.

I just installed SmartPack-Kernel Manager (ROOT) from the playstore. Open the app and click the hamburger on the top left. Go to CPU and change the Maximum Frequency. Swipe over the Apply on boot.
I turned mine down to 1382 and I can make it to about 25% before it starts to reboot. We will see if that is good enough for the kids.
Thanks for sharing, will try this too!
I have had the tab sent back under waranty but the problem returned.
At first manifesting itself using a boating navigation (navionics) but this morning opening the play store also rebooted.
After recharging when making a backup AND trying above solution at 40% battery I could at least start navionics, which was hard before.
Edit:
Rebooted below 23%, changed cpu settings but forgot to reboot to apply.
Now at 11% and navigation still working.
Edit2:
For the first time in I think over a year I have been able to use the tablet for hours on end!

Thanks a lot, it did indeed help. I set the frequencies using Kernel Adiutor and for the first time in weeks I was able to use the tablet below 50% battery.
