Naztech 3000 mAh extended battery - avoid like the plague

I got a Naztech 3000 mAh "extended" battery, since my stock one lasts for around 14 hours on a single charge. I figured I may add an extra 6 hours or so, or use my phone a bit more during the day.
So, here's what happened.
Day one: 4 hours after I charged my "extended" battery, I was down to 15% charge. 1 hour later, it was at 1%. I hadn't used my phone AT ALL. Charged after 6 hours of (no) use.
Day 2: Pretty much the same.
Day 3: Ran Battery Repair and wiped battery stats. No change.
Day 4: Used my phone heavily, and noticed it stayed at 1% for a couple of hours.
Day 5: Noticed a pattern. The battery will drop to 1% within 3~4 hours of use, and will stay there for around 9 hours. Then it'll turn off.
So, the "extended" battery lasts for some 12 hours - tops. 3 hours after charging you won't know how much juice you have left, since it stays at 1% from that point on.
Bottom line: don't waste your money, the battery is crap.

I have the same issue but not with that battery, i've been trying to find a way to fix it, none of the battery voodoo has worked for me yet
after my phone shuts off because it thinks it's dead and i plug it in to charge, within 2 minutes i have about 20% or more charge in the battery, then after 15 minutes it's about 50% or more charge.
is that same thing happening to you ??

Sort of, yes. It charges in half an hour, tops - if the phone is turned off. If I then turn it on, the phone shows 40% charge, or so - and tops 10 or 15 minutes later. Bizarre!

Happens to me also but only with the replacement battery i have.? It discharges fast and stays at 5% for a few hours. The OEM Battery 1880mah works fine about 1 and half day

I am having the same issue with my OEM Battery.Is there any solution for this or can we set the indicator to show the charge according voltage of battery bcoz i have noticed that charge time is good only indicator is not showing it accurately .My phone last full charge lasted more than 17hrs but it was on 5% in 2 to 3hrs of use.

Update: Today my charge was at 100% at 10.00 AM. With light usage, the phone died at around 5.30 PM.

My battery seems to report better percentages of juice left if I use Kholk's kernel, but I'm not sure exactly why. It doesn't go along very well with Faux's kernel, though.
...can't say much about the factory kernel. Haven't used it much myself.

Actually, the atrix doesn't support aftermarket batteries. Motorola says so, and Mugen says so. That battery is fine, you can use it on 1% for a while. And when it dies charging from 1-99% is accurate for my battery. But when you hit 100% all bets are off.

Did you turn phone off to charge, and pull battery and after it boots to a ?. You should let it sit there for a while and try again.

Mugen has an extended battery for the Atrix:

Of course, that one is $119, so it probably will work as intended...
Yesterday I got 6 hours out of my charge. I got fed up and swapped the battery for the stock one. $25 I'll never see again...

[Q] Battery drop after reboot?

I've been experiencing huge battery drops (from 10% up to 20%) after I reboot my phone. Is this a KitKat issue or is it my battery?
In the morning from 99% (after checking a few messages in the morning), I rebooted and I dropped 11% to 88%.
I think It may have been my battery giving me the huge drops. I don't seem to have this issue any more after buying a new one. :good:

I didnt found it on reboots, but i have this problem when i enter recovery. 20 minutes in recovery - i dont hace 20% of battery.

Hmmm that's strange.
I've noticed it usually drops more when I leave my headphones in.

full loaded ACE 2.
reboot cost u 5%
first 10 % gone in a few minutes for heavy users and in a few hours when deepsleep !!
what i wanna say.
the first 10 % gone in a few.
after that normal drain.

I often get this, although not as bad. I usually lose 2-5% on a reboot, sometimes up to 10%. The other week I charged it to 100% when it was off, turned it on and had 92%.

so is this actually a problem or is it normal for everyone?. Mine looses 5-8% in the first couple of minutes after I unplug the charger..

It's normal.

Its normal. I usually lose the first 5% of a full charge in a couple of minutes. After it gets to 95%, battery charge will drain normally depending on usage.

ok then, thanks...I just thought that this didn;t happen when I was on GB, but it doesn;t matter anyway..

If I reboot once, I will lose between 5 - 10% battery. However, if I reboot straight after the first reboot, I will lose between 0 - 2% battery. I've never really understood this.

Phone need more energy for reboot, that causing the drain. Mine usually drop 2-5%. After recharge battery alsi drop to 95-92% fast. Thats normal

Battery Charging Issue
Is this normal?
When I charge my battery whether it be from mains or USB computer it charges ok, but as soon as it gets to 100% it still says charging for a little time and doesn't report the unplug charger message right away.
With the Jellybean 4.1.2 system I don't get the alert tone when the battery reaches FULL, therefore I have a feeling that when it still says charging even though it's showing 100% that it's actually decreasing power at that point, any help please?
I have tried other batteries, and one in particular goes from 90% right up to 100% and seems to miss that last 10 percent, so I don't use that one now.
I have the most current firmware installed.

Buy a new one

when it says 100%, you still have to wait for a few minutes before it displays the green "full" icon in the upper left corner and asks you to disconnect the charger.
However, the first 5-8% always drains REALLY fast and not proportionally to the rest of the battery drain...

I think It may have been my battery giving me the huge drops. I don't seem to have this issue any more after buying a new one.

what about the initial drain? does the first 10% still drop fast or has this changed too with the new battery?

I just wish that JellyBean 4.1.2 would give an alert sound when the battery has reached it's full limit like Gingerbread used to do.
Who would be the best place to ask them to do this on their next update?

But I think that it does..a very short one indeed, but it does, along with the screen lighting up briefly..

Doesn't make a sound on my phone and im not always looking at my phone to see it light up.
I have sounds all turned on and on full volume so no reason why I dont hear a sound when its reached full capacity.

are you using custom battery ? like double-powered-battery

Battery charge problem...stops at 96%

my galaxy tab pro 8.4 stops charging at 96%....
i always charge it from 10 - 15% to 100% by switching of the device...from past week it always stops at 96 and when i switch it on it goes to 100 in a cou[le of minutes...what i s to be done ..i calibrated also..no change..

Yep, you have custom rom? that's usually what happens.
I have the slim rom and mine is like that, I just unplug and then plug back in does the trick

Custom rom has nothing to do with it. I am running the stock version, and my battery won't charge up more than 64% right now. It seems the problem starts with 96/94% but gets progressively worse. Sometimes it will fix it self for a short time when I replug, but right now even that doesn't work for me.
I checked last night, and I believe the kernel just thinks the battery is nearing it's 100% state. This was a screenshot I took that shows that the battery isn't charging at full power. The closer I got to 64%, the slower the charge went:

Have you tried just using the tablet when it was "fully" charged to 64%? I see three possibilities and I would be curious to know was the case:
1) Your battery is only charging to 64% and when you start using it, it will decrease at a normal rate and you'll get 1/3 less time out of the charge.
2) Your battery is showing 64% for all charges >= 64%. So, it could be at 100% charged and will stay at 64% until you've used up 36% of your battery.
3) It is scaling wrong so that 64% == 100% and the battery percentage will decrease as you use the tablet, but it will decrease 1/3 slower than it used to (aka the time from 100% to 0% when you first bought it would be the same as your time now from 64% to 0%).
Any idea which of those three is actually happening?

Definitely the first one. Right now I am at about 35% and have 2.5-3 hours screen time since the 64% (can't check for a definitive screentime as the indicator doesn't reset unless you charge to 100%). So that would translate to the about 7.5-8 hours I get when I do have a full charge.
I also checked once before when I had this issue by letting my battery completely discharge and then start up my tablet again and I had 1% left, so it was pretty much completely drained. I'll probably charge it again tonight and I expect I will have an even lower full battery percentage.

Try using a different 2amp charger and/or different cable

The only real fix for this opening the back up and unplugging the battery. When you plug it back in you won't see the problem again. Not sure why.... But that's how I fixed mine. Been good for two months now.

Also tried that already. Still only charges up to a lower percentage. Only thing I haven't tried is unplugging the entire battery.
It charged up to 100% for some reason last night. The only thing that is really weird that it charged 1% every five minutes from like 85-95% and then suddenly in the last 5 minutes it instantly charged from 95 to 100%. The whole battery thing is just really weird.

Could this be the solution to battery drain?

Hello,
For those with fast battery discharge problem, could make me doubt.
My ZF2 was also very fast draining the battery by about 20% in less than an hour with low use ... then did a test.
Let the battery becomes zero and put to press so super economy, when he got 100% left in the same way for about 1 hour and went back to normal mode.
Now after five hours, I have 88% battery, scoring 1 day and 7 hours left !!
Whenever you put the phone in normal mode, and leave this mode to load in 30 minutes consumes about 20%!

Hello.
First q: So you do this every time you charge your phone?
Second: The phone is charging continusly so regarsles of the drain it should not be a problem until you unplug it. Sorry i give it a try but i don t understand.

Always i carry it in super economy mode, after disconnecting it from the outlet, I let the super economy mode about an hour. then return to normal mode. I realized that by doing so, the battery lasts much longer. I think the trick is to leave the cell phone in economy mode super sometime after take unplugged.
Sorry .... I'm using google translator kkk

Won't charge to 100%

Anyone having an issue with their phone only charging to 98%? It will only each 100% if I unplug it for a bit once it reaches 98% and then plug it back in.

not seeing that on mine.

It does this by design. It prevents battery damage and prolongs battery life (in terms of life expectancy and usability over years).

I've had the 98% issue since day 1. I've never seen 100%. It appears to be a very rare issue. Otherwise my battery performance is great!

that happened top me on my first charge
just give it a couple charges it will start going to 100

I have to say battery life is great for me on pixel 2 xl. every time i charge it will go all the way to 100 %.

Hmm, I've charged it overnight for awhile now and it still won't get to 100%. It'll say that it's fully charged but will just show 98%

Experienced the same thing on my Pixel 2 XL. I did manage to fix it by powering the phone off for 10mins with it plugged in/charging. Once rebooted it showed 100%. Otherwise it will stay at 98 or 99% forever...
Strange thing happened yesterday. It finally charged to 100% and 5 minutes later I unlock the phone and its back down to 99% while still plugged in to the OEM wall charger (showing charging rapidly).

Copy and paste from my post in the Real Life Review section:
I would leave my 2 XL charging overnight (stock charger and cable) and when I wake up around 7-8 hours later, the percentage would either be 97%, 98%, or 99%. I've rarely seen my phone go to 100% since getting it on the 18th.
Whenever the battery hits 50% and I go and charge it mid-day, it would take a painfully long time to charge up after around the 85% mark (the general consensus and expected). I would check and it would be at 99%. After around 10 minutes, I check again and it shows 98%.
Needless to say, I disabled "show battery percentage". If the battery icon is full, then it's 100% to me.

I have this with my 2 xl too. It'll stop at 98-99, and if I unplug/plug back in a few times or reboot a few times it'll eventually get to 100. But it'll drop from 100 only after a few minutes even unused. Not sure if by design or a minor hardware issue.

Mine was charging overnight to 100% now for the last 2 or 3 days it's only been going to 98% overnight. Battery life is still good though.
I was wondering of was something to do with Battery Stats, maybe needs cache cleared or resetting somehow.

Actually I cannot even get mine to charge to 100%

Actually I cannot get mine to charge to 100 percent except two charges ago. That being said there must be something wrong as using the white charger and cable to go from 2% - 98% it took more than 5 hours ! I cannot get it to go past 99 % and I have been charging with phone off then with on and then according to Google support tried safemode but still no difference. Highly frustrating for a $1k phone. I finally shut phone off for the last 20 minutes and then checked the charge and it is now at 100% but what a battle and a SLOW SLOW charging phone.

I never charge mine to 100%, I usually take it off the charger around 85%. Not had any battery problems, don't think it's ever necessary to hit 100%.

I've had the opposite. Wake up it's 100. Listen to music on the way to work for about an hour (bluetooth). When I get there it is still 100 percent. Put it in pocket for another hour, check phone, 96%.

I turned off my phone when plugging it in last night hoping to make this go away.
When I turned it back on this morning... still only 98%...
