Why not update to B14 and see if it helps?

 

Anyone who thinks this device has poor battery life... obviously has something incorrectly set up on their phone. The great battery life is actually a selling point of this phone. Granted, it isn't as good as the original ZMAX due to the higher resolution screen using more energy, but it's quite good. I usually get a full day with heavy usage.

 

I think it's somewhat unfair to assume that the problem OP is having is a result of how their phone is set up, a defective unit is very much a possibility

 

I hope it helps

 

I'm going to replace my phone at t-mobile tomorrow since I think my phone is defective. It gets hot and the battery drains way too fast I go from 100 to 70 in about a hour of moderate usage. I left my apartment at 4 this afternoon with 100% batter I did some light browsing to read some articles and went on twitter and by 6pm my battery was below 30% I have it on my external charger now.

I'm definitely going to get my replacement tomorrow.

 

Geez!
Only thing I can think of that could cause such a drain would be if your area has very spotty coverage. The device switching between 2G/3G/4G constantly will consume a lot of battery.... but still, you'd have to be living in the mountains to have such bad reception these days.

I used to work in a building that had a secure area with cell jammers. I'd have to go through 2 full batteries a day because my service constantly dropped and picked back up a minute later.

 

Here's mine after 4 days. I keep my screen brightness at about 25% and I try to keep the background apps at a minimum, also I don't use battery saver. I never have network issues or anything either, don't know how much that would contribute though.

 

When was the phone manufactured? I got this phone as back up recently and it said it was manufactured Jan of this year, 2017. I also did the system update the day I got it. Battery is extremely good and lasts me the whole day and goes into the second day with some 50% still left.

Hope you get everything fixed.

Edit: Mine is a T-Mobile phone.

 

It seems to me that you can discharge this battery, but you'd have to try. It lasted me 2 days previously, but you can also drain it in 4 hours with maximising your use of everything, especially the screen brightness.

 

I should be getting my replacement this week..

 

What icon pack is that? It looks great.

 

So I just picked up my replacement device. It's on on B04 I'l update it when I get home to wifi and see if I still have the same problems after a week.

Yeah, my roommate and I both have the ZMP, and for both of us, excellent battery life. My battery drains faster when I have Bluetooth on, obviously, but even connected to my BT headphones all day, the battery lasts longer than the one in my Galaxy S3 with everything of, screen off, and just sitting on the nightstand.

 

Battery life is quite awesome far as my replacement goes, I still haven't charged it yet. I'll test the battery again.

 

My question is, why the hell did ZTECH hardwire the battery in the first place? Maybe they didn't want to be like V-Tec, the cordless phone mfr who offers a replacement battery as the first accessory. Or the HTC G1, where battery makers faked the code on the label to make customers think the batteries were OEM instead of low-quality, won't-run-your-TV-remote-for-a day sh*t.

Day 2 with my replacement, so far so good. I'm going to put it to the real test on my off day from work.

 

Day 3...it actually lasted me the whole day with moderate to heavy usage. Tomorrow is the test 2 to see how good my replacement phone battery is since I'll be off from work and I get to really heavily use my phone.
