Anker 2050mAh extended battery (same back cover)

---

Alright so recently I purchased the [url=http://www.amazon.com/gp/product/B0078WL4YO] Anker 2050mAh battery. It's compatible with the T989 (Hercules) and I727 (Skyrocket). It fits in the standard battery cover.

Like my previous Anker batteries, this one arrived with 66%. I used Juice Offender to drain it to 0%, and then fully charged it.
I later used it moderately throughout the day and it lasted about 16 hours. 4 hours on 4G and 12 on Wifi. I DON'T have screenshots though. By moderate use I mean quite a lot of texts, IMs on Facebook, checking Facebook every half hour, about 30 pictures taken in 8MP resolution (without flash), a few quick calls with Google Voice, a bit of web browsing, about 30-45 minutes of gaming, and a few YouTube videos streaming on 4G in high quality.

The next day, I used it on a full charge. The screenshots are attached. I used it moderately/heavily this time. About 3 hours on 4G and 10 on Wifi. More texts, IMs, pictures, 6-7 minutes of HD video recording, streamed more YouTube videos in high quality on 4G, an hour of gaming, some web browsing and dictionary use, and 2 very short calls. As you can see in the screenshots, my phone was awake quite a lot.

NOTE ABOUT THE SCREENSHOTS: The battery isn't at 81%. It really died, and when I put my stock battery in, the battery stats continued (which is really strange) so that's when I took the screenshots. If you look at the chart you can see it went all the way down and then a sudden rise up to 81% at the very end.

Note 2: When Wifi was on, I was using Wifi calling, so the phone signal was turned off.

Note 3: This is on rooted stock ROM + stock kernel, with almost all bloatware removed.

Here you can save money by buying two batteries + the universal Anker battery charger. The charger can charge almost any smartphone battery by lining up the metal contacts properly. It can take power by plugging it in a wall outlet or by a USB cable connected to a PC or wall outlet. It can also charge a phone by connecting a micro USB cable from it to the phone. So you can charge two batteries at once.

Awesome,thanks for the review!

This is great.

I used Anker 1900mAh for my sensation and it significantly increased battery life compared to HTC battery. Hope this battery does the same to my T989!

Update: I just bought one. Will try it for few days and update here on how it works!

I'll be watching this thread. I've been wanting to get this, but this is the only review I've found so far.

One thing that caught my eye is that Ankor says "Keep the battery power between 5%-95%", but i like to plug in my phone/battery and just let it charge while i sleep or whatever. I wonder if my habits of just letting it charge until i unplug it will negatively effect the life of the battery.

Things become abnormal when too overly do. I suppose this is the common rule.
Some batteries may not have the "overcharge protection", and if it is not protected, battery life will be shortened. And for me, even if the battery is protected, I will still use it with care.

whoever tests this out, can you guys also use DISPLAY ON TIME and VOICE TIME if you use that. (2 main factors)

What type of usage did you get with the stock battery? At that price I may pick one up.
I'm running an aftermarket rom and tend to get that already, but I'm not too sure what stock debloated is capable of with the normal battery. it's Amazon prime too, so i might order it tonight and see how it does this weekend.
EDIT: Damn, or for $10 more a second and a charger. 2 of my immediate family use this phone.... hm....
Further edit:
would this one fit?

Thanks for posting this, just ordered a pair.

Looks promising.

I got about 23hours on one charge off these batteries

Is it worth it for the extra 200 mAh?

And in the description for the batteries, Anker says:

Using Tips:
- Keep the battery power between 5%-95%.
- Avoid overcharge and over discharge. Please stop charging when the battery is 100% charged.

Should we maintain batteries like this because I heard otherwise?
