Nokia, 19 Jul 20163310 is about an inch thick but we didn't care, and it lasts a week or more.Indeed, on a 900mAh battery. Rather than asking for ever bigger batteries, we should ask for a (much) lower standby power draw. Very few apps HAS to run, or even be in RAM, when they're not on the screen, and certainly not while the screen is off.
Make the essential stuff run directly on the baseband and power off that big SoC completely when we're not gaming or doing heavy photo filtering. Just snapping a pic or typing an MMS doesn't need GHz.
My Zenfone 2 barely can make it through the day....maybe on power save i get bout a day and a half with minimal usage like wifi and maps...
Battery autonomy is IMO one of the biggest drawbacks of smartphones. I agree with what's been said before that people would gladly take 3mm thicker phone with additional 2000mAh. I only wish more manufacturers (not just Chinese) would realise that.
Until then... Chinese phone it is. Gsam battery monitor on my Oinom LMV9 with 4500mAh says 5d 20h battery life and 9h screen on time per charge. Thou now that I stopped fiddling with settings and apps it lasts one week :)
Oh, and no games on my phone.
Pretty pointless survey.
My Nexus 5 can last two days or at less than half a day. It can go crazy with the battery if I enabled data-LTE or run a 3D game. Using both at the same time would be too crazy.
I would like a battery life where I can leave LTE, Wi-FI and play a 3D game during my commute and have charge remaining when I get home.

Yeah, 2 day would be great, to cover the night you forgot to charge the phone.
Ideally, I want 1 week.
I have a low end phone with 1GB ram and 2000 mah battery. It lasts 1-2 days with average usage. Battery capacity isn't as important as user interface and software optimisation. My second phone is Sony Xperia Z3. It has super battery life.

Personally, I don't care if my phone has 7-8mm or maybe ~10mm thickness as long as it's not awkward to hold/comfortable to hold
AnonD-77322, 19 Jul 2016Battery is not keeping up with the rest in my opinion, 4000 mAh should've been standard by now....Totally depends on the screen size but yes, 4000 mAh for a 5.7" screen, probably 3000 for a 4.7".

franz.alex, 18 Jul 2016I'd say that half of the problem with today's crop of phones is due to manufacturers' mad rush... moreI've started using a smartphone for 5 years when better screen, 3G was fast enough and you could start doing a lot with it. Every since, swappable removable battery was key in getting a great all day usage. And i have moved to extend batteries and eliminated swapping batteries. 10,000mAh battery is something. Directly powering my device. No nonsense having to charge in the office before going home.
People, powerbanks will only give about 70% of what's indicated, just another thing to charge and even bulkier than extended batteries.
If you didn't know it yet, all that wireless and fast charging are short-term solutions as they degrade that battery even faster that you expect that sealed battery not functioning in 10 months.
Anonymous, 18 Jul 2016Like this is new to phone makers lol. Making us buy new phones yearly is their goal, not givin... moreNo, some of them listen (Partially)
Samsung listened in Galaxy s7
Huawei listened well in their honor series (4000mAh)
I'd say that half of the problem with today's crop of phones is due to manufacturers' mad rush to producing the "thinnest" phone.
It wouldn't be surprising to find that the vast majority of people wouldn't mind getting a phone whose thickness is around 10 millimetres provided it would assure them enough power to get through a day or two.
That said, we may as well consider a return to removable batteries. It's far easier to carry around one or two replacement batteries than it is to carry a charger. Plus, a quick battery swap and you're back to 100% capacity in about a minute. No fast-charge can beat that!
It may be overkill alright asking for 12 hours SoT. However, it is worth pointing out that many phones out there cannot reach 8 hours SoT *with* user activity. If only devices could maintain a decent level of usage for the average user then we'd have met power users halfway. As it stands now, power users have to spend quite a lot of time hooked up to a wall or carry around a battery pack to top up when the limited internal batteries are running out.
Okay people I need to apologize here. I voted twice cause I wanted to see if it was possible to vote more than once. I suppose Samsung fans must've been really voting multiple times then.
sa11oum, 18 Jul 2016Perfecting fast charging is the answer. We'll have to change our batteries faster than now due... moreSupercapacitors are the answer for this then. They have way lower power density than a normal battery (about half or 1/3) but can charge in seconds literally.
You'll just need an expensive charger if this is the case, something like a 20 A charger.
If you're curious about supercapacitors and how one behaves in real life, there's car battery replacement modules, you start the car with it and it charges in about ~20s to full charge. Handles some cranks, but won't hold charge for more than a week before needing jumpstarting: https://www.youtube.com/watch?v=z3x_kYq3mHM

Solar panels could be way more viable if battery technology allowed it. Samsung tried it with the Blue Earth model but the big catch is: Lithium Ion degrades badly if charged at high temperatures, and leaving the phone on the sun does exactly this. Not to mention picking up a burning hot phone.
For now on it seems like improving power efficiency is the best possible scenario, the only one that will allow alternatives to be even close to viable. While we have those ~5W phones draining power from all hardware around it I think it's gonna be hard.
I think I've heard about graphene being being used as an anode/cathode for the battery. If this becomes viable to mass produce it could bring a big revolution to the battery duration scenario on any portable device/vehicle. I just hope manufacturers stop with this stupid trend of making devices thinner every freaking second, this alone could help a lot.

- watches been doing this with kinetic energy harvesting, and there's Peltier effect that you can get energy from heat itself. The efficiency improvement on all parts is the key to make it work
---> well, I guess it's called kinetic energy by human movement.. actually there are this kind of charger available in the market, plug it into ur phone, the catch is you need to swing it to charge.. As for Peltier effect, it's quite complicated to make it more compact, and like your saying before it is still not efficient
Wireless power transfer:
- Tesla did manage this, the problem with it is that you need really high voltage. Also any open coil could potentially become dangerous by simply being there rolled up.
---> there are some research indicating there are effect to human body from this kind of wireless power transfer, so it may be not safe for human, the more voltage the more dangerous to human.
-that one I kinda agree, way too far fetched and complex for a phone only. If we can't even make it into a ship, let alone a car, a phone is beyond thinking for now at least.
---> and the person who got this idea wants it fusion reactor, not fission reactor. We can see this kind of reactor on our phone IF Tony Stark exist to this world, using his arc reactor to power our phone, and even that tiny arc reactor more than enough to power our car or maybe a copper or small jet :D
Body energy harvesting seems to me like the most viable option, although there has to be some secondary power source for when you're not close to the phone.
---> well, I guess the most viable option is solar powered, put a solar panel behind display (or back) just like Tag Heuer meridiist infinite although it's still not enough but at least can make your phone last longer substantially. Or, we just wait nano-technology based battery, using nano-technology construction to create battery that can store more power than today battery, I think this type battery might come sooner than mentioned options above.
Battery life is fine. What I'm more worried about is battery longevity. There are several technologies out there but manufacturers want us to buy a new phone every two years, so they don't bother changing....
