Extended battery

**bruce7373** · 12-14-2012, 12:28 PM

I'm thinking about getting an extended battery for my Vivid and am considering the GTMax. I'd like to get a better back cover, though. I've seen some Mugens on eBay, but not for the Vivid. Any other place I can look?

The case or the battery?

Just the case (back cover), which apparently will fit over the GTMax. The Mugen battery itself is a little too pricey for my needs.

Hmm...I would look on amazon.com, but it might be hard to find it.

Yeah, already checked Amazon. Nada. But the more I look into it, the Mugen cover isn't so hot either. I may just pop for the GTMax and just be bery, bery careful. Lol

Or... Has anyone any feedback on this battery:

I use this and get amazing battery life. The back is decent but could be stronger. I'm a heavy user and I get about 16 hours on average.

Good to know. Amazon has it for $10.70, although it's not ID'd as a GTMax, just X710E, so I assume it's the same one. I've got about 10 bucks in credits, so it'd be hard to go wrong.

They also have a GTMax 3500mAh for $13.94.

EDIT: No, I'm wrong. The one you have is the is the $13.94 one.

This is my battery. Just so you know...

The Q cell battery actually works for my phone, plus it's cheap, and its available on Amazon and Ebay.

Thanks for the suggestion, Vern, but I just ordered the GTMax from Newegg - - free shipping plus they're close by, so I should get it fairly quickly (thanks OperationA7X).

Here are my stats so you can have proof.

So, the GTMax came today. The back cover isn't nearly as tacky as I was led to believe reading some of these posts. I can see the clips are pretty delicate though, so I'll try to watch out.

It came with a 60% charge. How many times do I need to do a full cycle charge to break it in? 2, maybe 3?

**OperationA7X** · 12-21-2012, 12:23 AM

I did one for like, 6 hours and it works great.

Well, I hope this is a good sign: I did one full charge and have now being using the phone for 2+ hours (reading news feeds, surfing, writing emails), and I'm only down to 93%. Normally I would have used at least 20% by now. :-)

**OperationA7X** · 12-21-2012, 03:42 PM

In my experience, it takes a few drains to get full length. But hey, its worth it. I know the clips are weak, but hey, its worth it.

Looks like you get what you pay for. The battery failed after one day! It drained to about 55%, the phone went into sleep mode, then when I tried to wake it, it wouldn't turn on (even plugged into AC). At first I thought my phone had died, but I put the OEM battery back in and the phone booted up.

Bummer.

**OperationA7X** · 12-22-2012, 06:52 AM

That seems very odd...I have never had that before. So, the battery is dead already, as in, won't charge anymore? If not, it was just a bad charge cycle or the battery really is dead.

RAll I know is, it was at 55%, the display timed out, I tried to turn the phone on a few minutes later and...nada. I kinda panicked, thinking the phone itself had died.

So I tried plugging it in, but it still wouldn't turn on (no charging light either). I took the back cover off, breaking a clip in the process (sigh), replaced my OEM battery, and I was good to go.

So I don't know what's up. Maybe a connection problem and the phone doesn't "see" the GTMax all of a sudden, since technically the phone won't run on AC if it doesn't detect a battery present, right?

Edit: I just did an experiment. I plugged in the phone and turned it off. The charge light stayed on. I pulled the battery and the charge light turned off. I put in the GTMax. No charge light. Replaced the OEM and once again the charge light came on. So clearly the phone isn't recognizing the GTMax for whatever reason. Maybe something got fried when I was playing Angry Birds, lol.

Eh, that or its just a bad one. A lot of extended batteries are hand made, and sometimes, you're bound to find a bad one. But my guess is that its 1 out of every 5,000.

The Q Cell battery is still working great for my phone, I've read a lot of reviews aboot some of the other batteries being junk. I bought this one after reading many of the sellers reviews on ebay.

Thanks for the update, Vern. I'll check it out.

Edit: Do you have a link? I've searched on Amazon (not available), and I get no hits with either eBay or Newegg. If it's made by Samsung, it's probably only for Samsung phones.

**Vern441** · 12-24-2012, 11:35 PM

I bought the Q Cell from Amazon, I just used the Ebay reviews to see if the battery worked. It was problematic at first trying to find the correct battery for my phone, but then I came across phone cases that would fit my phone that said Boost Mobile Samsung Galaxy SII SPH - D710BST or Sprint Samsung Galaxy SII Epic 4g touch SPH - D710, Boost uses Sprint towers, after that I realized it was the same phone. You might be able to cross reference your model # if another prepaid carrier that uses the same network as yours sells a similar model phone. It did take awhile to find it so do your homework, and don't hold me responsible if you get it wrong. Just trying to help you out.
