Hello, seems like there's a better battery out there claiming to be the world's largest Galaxy S3 battery

ZeroLemon Samsung Galaxy S III 7000mAh Extended Battery + Free Black Extended TPU Full Edge Protection Case

Can anyone confirm this battery result? Seems like the battery is physically larger according to the pictures too making it seem plausible for larger capacity. Also a TPU case too. Does it have 3x the power as they claim?

If this works as they claim, it seems they are going to wipe the floor with those QCell, hyperion, mugen, anker solutions

UPDATE Feb 28th: Spoke with Joey at ZeroLemon and they are phasing out the 6300mAh. Now they only have the7000mAh available. The 7000mAh battery is confirmed to be 1mm thicker than the 6300mAh to facilitate the extra 700mAh. Just got one at 31.99 (still best mAh / $ battery out there ) and will post some results after a week use

JAN 21 UDPATE: I'm posting my review here which is same as post #16

Just took a shot and got and can give some brief insight between this and the hyperion i got.


ZeroLemon with included TPU case:
Length: 13.9cm
Width: 7.3cm
Thickness: 1.6cm

Hyperion with hyperion case purchased seperately:
Length: 13.9cm
Width: 7.4cm
Thickness: 1.8cm

This is pretty much a huge battery with an Extended TPU case that Hyperion and Qcell sell on the side for extra 6-8 bucks. The way they acheive larger capacity i'm assuming is that they take full use of the back of the phone physical dimension (in areas such as where microsd is, the battery overlaps it). That's very unique approach that I have not seen another one else has done so far. Since the case covers the battery anayways, you will not notice these throughout regualr day use.

There is no back hard back plastic cover like the Hyperion one as the extended case does the job in securing the battery in place. A thing to emphasize is that the thickness is literally the same as the Hyperion battery + the extended case or even slightly thinner as there is no hard plastic cover to add the extra thickness. In fact, how they hold the battery is by using the tpu case edges to secure the battery which is quite ingenious. I tend to have problems with those hard plastic covers used by hyperion because it doesn't secure properly and dust goes into the gap. With this zerolemon battery, the problem doesn't exist since there is no such gap.

Being a bigger battery, you can feel it is slightly heavier by approximately 20g. It's not really noticeable to me because the hyperion battery + TPU case is at most 10 g less than this battery (since the hard cover in the hyperion is 10-15g alone I think) The weight of the phone obviously is heavier than original battery but only around less than 10% heavier than hyperion + tpu case for at least 33% more battery life. If you carry this in a bag, this is very good.

For performance I cannot assess yet as i just got this, but it's been a day and I only got through 70% so far. very impressive since usually 1 day on hyperion for me is 30-40%. I'll give a more detail assessment once I get more use on this.

It's around 35 bucks for this zerolemon battery right now and I seriously think it's worth it over the hyperion battery. I got the hyperion battery for 26 dollars + the soft extended case for 6 dollars (Total of 32 dollars). It's only essentially 4 bucks more for an increase of 2100mah capacity.
UPDATE: Just saw it at 23.99 USD! Even cheaper than Hyperion's

Just working out to be:
ZeroLemon - 180mAh per dollar -> at 25 USD, this is 252mAh per dollars which is almost DOUBLE hyperion's capacity per dollar value!
Hyperion + soft case - 131.25 mAh per dollar

Just capacity per dollar this also better value than hyperion's.

UPDATE JAN 21st - After Lake Tahoe snowboard trip with very heavy use of GPS

just confirmed this is truly the monster I've been looking for!

I got ready for my weekend snowboard trip at Lake Tahoe from San Francisco.

Unplug my phone at 5pm
At 7pm drive up to Tahoe City for 4 and a half hours with medium brightness and GPS on the whole time. (made a quick pitstop at walmart )
Reached Tahoe City at 11:45. Phone is at 70%
Didn't not charge at all overnight

Went to snowboarding with GPS on again to Alpine Meadows which is 20 mins away
Went snowboarding all day while listening to music. Reception on top of mountain is a bit weak so may have worked the battery a bit. took lunch break and whatsapp some friends.
Turned on my wifi and start browing internet for a bit in hotel. Forgot to turn it off in between
Did not charge overnight

Went to snowboarding with GPS on heading towards Squaw Valley
took a longer break this time and start browsing anandtech and for around 30 mins
Headed back to San Francisco which takes another 4 and a half hour with medium brightness and gps on. (made a quick stop for dinner in between)
Did not charge at all overnight

Return my rental car and used GPS again at medium brightness.


-Battery finally finished by 12pm with 2d 16h 32m total use
- 13h 33m screen time on the battery at medium brightness (I set it back to medium brightness even when the battery is at critical level)
- GPS on for 10h and 36m

All this and not a single charge during the weekend. This is the weekend warrior battery I've been looking for. Hyperion does ok but dies usually by Sunday morning.

One interesting thing to note is that when the battery is at 3%, it will stay there for relatively longer than usual. I'm guessing it's the phone's OS not able to calculate the battery percentage correctly being so big of an battery.

This battery seems to do even better than at 6300mAh capacity. I threw this battery in my CBA tester tonight to check the exact capacity and post some results once it's done

UPDATE on CBA test:

The battery is rated at 6510mAh and below is the graph. Very good stuff

GPS use update:
21 hours GPS with 20% brightness! This is BOSS!
