36 hours of battery life from the iPhone 6? It's possible with the Fat Battery mod!

36 hours of battery life from the iPhone 6? It's possible with the Fat Battery mod!

In February, we wrote about a project which boosts the iPhone 6 and 6s' battery life in a rather dramatic fashion. Fat Battery literally replaces the handset's back panel with one that looks true to the original, but is much thicker in order to fit a large, nearly 7000mAh battery. In comparison, the iPhone 6s has a 1715mAh unit. Back then, the product was to cost $300 and customers had to send their iPhones to the FatBattery team to have the modification installed.

Just before launching this version, the project's inventors saw an opportunity to make a cheaper and more convenient one. So they took a couple of months off and tomorrow, April 28th at 9AM EST, you will be able to back a $129 FatBattery mod that lets you install the battery upgrade yourself, or simply take it to a tech shop. To get an idea of the overall benefit, a regular iPhone 6 lasted 13 hours of video playback, while the upgraded one held on for an impressive 36 hours and 24 minutes. That's constant on-screen use, mind you.

Despite that, how is turning your iPhone into a brick a better solution for improving its battery life than simply installing a battery case? The team at Fat Battery boasts that their invention gives more than double the punch of bulkier charging cases, yet it doesn't waste physical space on a plastic casing. 95% of the Fat Battery mod's added volume is used for improving battery life, which is very efficient. And unlike them, Fat Battery leaves the Lightning port open.

At first glance, it may not seem like it, but Fat Battery is, technically. a more elegant solution than a big ol' battery case. However, the installation does involve removing your iPhone's back panel – yourself or at a shop – which might scare a few people off. Still, if the campaign succeeds, the team at Fat Battery will introduce a version for the iPhone 7 and the iPhone SE next year.

That's interesting because my friend's S6 Edge manages around 10h total use with 2h SOT... She's regretted "upgrading" from her S4 ever since it arrived.

Smell what you like - I'm with her now, she took her phone off charge at 7:30am, it's now 1:15pm and she's not used it aside from reading a couple of emails and taking a 5 minute call, it's at 63%. It's s**t.

No, I clearly said S6 Edge, I didn't say S7, I can only presume they must have dramatically improved it...

i use s6 edge as well, battery is not great, i dont know where to check how much i get SOT on phone, well i do lots of browsing emails, sometimes videos etc, wifi and 4g always on. i can get full day of my phone. 8h SOT is probably BS. but it aint that bad, iphone is worse.

Well my friend's one is terrible, simple as that, I've no need to lie because I've got nothing against the phone. She even sent it back and they said it was fine, another friend who's better with Android went through it too to try and optimise it. My iPhone 6 is far better, the latest updates have knocked about 20% off of it for some reason but I'm on the beta program so can't really complain until full release.

Jimrod - My s6 edge+ gives me only about 2 hours screen time on average with minimal usage. I know fanboys gonna get butthurt, but the truth has to be said. Touchwiz sucks. I have to rethink my plans of getting the s7 edge now.

That battery graph basically means you have nothing running, and that you check your phone to see if someone called. Not much else. This on screen time, is hardly you using the device for watching videos or playing games. If you look at the graph we can even see when you probably got online or watched youtube, the deep dip in the graph shows that if you 'used' your device you wouldn't be getting 58hrs and that is not what 'average' user would get. I have gotten long battery stints (2days plus) out of my device as well...but I wouldn't go claiming this as 'normal' either. The 13hrs of web time that gsm got shows that the device will drain in within a day if you are a heavy user.

hardly use it? I got 8h SOT over 58h total use on 1(one) charge. I never said i played any games etc..I just said from my daily use I normaly get 30-45+ hours of total use with approx 6.5-8+h SOT, I don`t use AOD,BT on when I use it,WIFI most of the time,and brightness set on 50% auto.. I browse alot, FB, insta,youtube and some angry birds maybe 20min per day..thats basiclly it..

All I am saying is you are far from a 'normal' user. I have a phone that has the same browsing time as yours during battery tests, nearly the same talk time. I get regular 18hrs of good usage. Taking my phone off the charger at 4am and putting it back on the charger at 11pm. I also get long periods of low battery drain, like last night 7hrs some 2% when not in use, and I don't turn off wifi or BT during bed. So in theory, I can get 40-60hrs if I didn't touch my phone and use it sparingly which we can see you do on your phone through the battery drops. look at that big dip in battery, that is most likely when you actually 'did stuff' with the device. Normal user would have plenty of these ' bigger dips'.

Why is this needed if there's already a wireless charging case for the iphone?

If you are camping where there is no electricity you will love to have better battery instead of wireless crap charging.

if you are camping, and still that attached to your phone, then it's not camping.

I'm guessing the warranty is voided by this?

I will admit is cool to see a battery last for 36 hours, but in all honesty very few of us need that 20-24 hours would be perfect for most people.

So make iphone a bit thicker ( not twice ) and get good battery life. but apple dont want thats.

It's just a battery. Or don't get all excited when an update comes out, the chances are it will brick your phone or slow it down regardless.
