If you can live with a 21.3mm-thick LG G4, get this 8500mAh battery pack from Zerolemon
At the moment, one the biggest debates among smartphone fans is whether the current trend of ever thinner smartphones is preferable to the thicker phones with larger batteries. If you're among those that wouldn't mind a thicker smartphone as long as it offers superb battery life, you might want to check out Zerolemon's new battery pack for the LG G4.

As some may already know, the LG G4 comes with a 3000mAh battery. If that's not nearly enough for your needs, then the Zerolemon battery pack for the LG G4 can help you extend the battery capacity to a whopping 8500mAh, or about 2.83 times the capacity of the original battery.

Unlike most smartphones, the LG G4 has the navigational and power button on the back. For Zerolemon, this translated in a design challenge that the company overcame by making its own soft-touch plastic back case that implements back-mounted buttons. To make sure that the case doesn't hinder future NFC payment capabilities via Android Pay, the case also includes an NFC chip.

The 8500mAh battery pack takes about 3 hours to fully charge, but you're probably going to enjoy about three days of moderate usage. Just think of how many hours of video recording you can squeeze out the LG G4 with an 8500mAh battery.

As you can imagine, installing such a large battery doesn't come without its drawbacks. With the battery pack installed, the LG G4 measures 21.3mm across the waist and weighs 178g, up from 9.8mm and 155g. For a visual representation of how thick the LG G4 becomes with the battery pack installed, check out these official images:

If you're tempted to get the Zerolemon battery back for the LG G4, head over to the source link below, where Amazon is currently selling the battery pack for 59.99, down from the usual price of $89.99.

Wow, G4 is looking more beautiful than the original with Zerolemon on. I used zerolemon back in note 3. It was little thick but the back up was amazing. It was able to last 4-5 days in a signle charge with moderate use

There are also 3400Mah and 6150Mah on ebay that won't give it the hunchback effect so much

mugen power and hyprion are also worthy to mention

Stupid. The reason I demand a removable battery is so I always have a full battery and a slim phone. This is just dumb. A simple external wall charger and 1 or 2 spare batteries is all you ever need.

There are several reasons for a removable battery. Don't think your use is the only use. Thinking like that is why the manufacturers are going away from removable batteries--they don't understand the needs and wants of their customers, and neither do you!

I'd rather carry 2 extra batteries than this big fat dumbass.

I probably wouldn't like this either, but I like the option of being able to buy it. Makes the G4 much more attractive than the S6.

That's the only problem with the LG G4 poor battery life that requires you to resort to something like this. I think the G4 is a great phone just shame why it does not last no where near as long as the note 5 with similar battery capacities.

I think QHD LCD is the culprit. Samsung use Super AMOLED, which is more efficient in power than LCD at QHD resolution. LCD should be upto FHD display only

It's SD808, the screen is very efficient and drains slightly more than the 5.2" FHD screen on G2. And we all know G2 had amazing battery life.

A battery increase is needed, G2, G3 and G4 all have the same size battery

Install a custom ROM, Don't use Google services and enjoy 5 hours On Screen on even a tiny 1500 mah battery. The culprit of your battery drain are excessive background processes that waste CPU cycles and increasing display resolution which eliminates all efficiency gains by making the SoC work harder to render more pixels.

5 year old Custom SOC architecture (Krait) on the G2 vs Off-the-shelf designs from ARM. Which is the best of the worst? Apple is so far ahead in SoC design it makes me chuckle. They put out a completely new, CUSTOM architecture every couple years. Snapdragon 808, 810 and even Exynos are all based on Stock ARM architecture and are years behind Apple. Samsung has never created a custom SoC to this day. And Qualcomm hasn't released one for 5 years.

Exynos 7420 is the best smartphone CPU and GPU in the world ALso, the onscreen GPU benchmarks are useless, because each device will run different resolution. In offscreen (all running same resolution), Exynos 7420 is always faster than A8 and snapdragon 810

Unfortunately Samsung lie about 14nm Soc aka Exyonse 7420 it's not an 14nm build it's 20nm check anandtech.com.

"... the onscreen GPU benchmarks are useless,..." Eh? It's the other way around. Onscreen benchmarks is what you actually feel and see when using the device. Onscreen is what REALLY happens when you're playing a game or watching movies (provided the device can decode fast enough). I'd rather have a 50fps each and every time when I play a game (no matter what kind of game) than some sorry-ass that falls back at 12fps due to a ridiculous super-high-resolution. Besides, isn't 1080p enough?

SOC’s are NOT offenders for Thermal Throttling - it is vendor decision how aggressive they want to run SoC. Samsung could have decided to run S6 more conservative even when cold, like Apple does with A8, which would result in lower overall performance but also in low difference between best and worst case. If you want to compare SoC's , then compare their sustainable (worst case) performance in those phones. For example, Exynos 7420 geekbench score is 4864, while A8 is 2927. Now, if we assume those are 'best' scores (ie if geekbench is short benchmark rather than long one where mobiles would already throtle), and if we apply 40% throttling to 7420 and 10% throttling to A8, we get 'worst' case numbers for 7420 as 3425 geekbench score, and worst case for A8 as 2637 ... meaning that 7420 is still 30% faster than A8 , within presumably same thermal range (ie range allowed in mobile phone) In short, it is HTC that is offender with SoC throttling, not Qualcomm. Qualcomm is 'merely' offender for creating underperforming SoC. Apples CPU are sub par. They don't come no way near Exynos. Lmfao. Says the iFanboy.

As much as I hate apple, their SOCs are actually very good for their performance/watt. The A8 has a very potent GPU that consumes way less power than the T760MP6 or the Adreno 430 and considering there are only 2 CPU Cores the throttling is WAY lower and the GPU does not throttle whatsoever. I personally have an S6 and after 5-10 minutes of heavy 3D gaming (dead trigger 2 ultra settings, modern combat 5 modded to have the best graphics possible) the GPU throttles quite a bit and there are noticeable frame drops. Though the only reason the A8 doesn't throttle much is because the resolution sucks d*** and the GPU isn't doing much work compared to the 1440p display of the S6. Oh and its not HTC's fault... Its Qualcomm and there complete trash of a SOC, the 810. It overheats like a b***h so much that Sony needs thermal paste and copper heat pipes to cool it down.

And non of Android flagship to date can beat Apple in single core not even S6 with Exyonse 7420.

The G4 could have been a great phone. As it stands it's a mediocre phone with a good camera.

It's about moderation and balance between size and battery life and this mod is way on the other end of the spectrum of being too big. The sweet spot for battery size and capacity should be optimized for all day (6AM-3AM) heavy usage (not ingress heavy usage but something in line with browsing, several hour streaming lte audio/video, 2 hour gps commute + errand usage).

Yeah about 5000 mah should be enuf and thats would only add a few mm to any phone. this is also amazing but only for ppl like me thats are super power user.

Better to carry a power bank when needed..

Not really as you will need to keep the battery pack plug in the phone and if you need to use it then its not very good. Moving around a plugged device increase chance of breaking charging port.

Powerbanks are useless after 2 years when your battery is dieing out and you want to hand down your device to a less fortunate family member. Or want to sell it to make some money for the new gadget. Unless you're an egocentric rich bastard who can afford to throw away a +500USD device in the trash to buy a new one or dupe the guy who wants to buy your old device. How futile are our problems these days....

I'm confused. Why not just carry an extra spare battery or two of you just can't stop using your phone to that point. Spare batteries don't take up that much space. This is even better than quick charging. 0-100 in a couple seconds.

And you can remove G4 battery yeah at Telus in Canada we even offer a free extra battery + 32 gb sd + a charger thats can recharge the battery whitout the phone.
