I'd say adaptive charging is a good compromise. 900mA during 01:00 to 06:00, user-selectable turbo charging.
Background apps are turned off. Unless I have Viber or a web page open. There are probably more processes running in the background that would require a force shutdown in the options. Never really checked. Id heat gun the surface of my phone if I could. I wouldnt be surprised if it was charging via the included charger, it would be 40C. I still use it from time to time. Sometimes I need a quick charge. However, I prefer in any situation to let it charge at a slow amperage. Just to be safe.

I really hope you are kidding/joking. In 2002 i was using an old sony Ericsson T200 i think and it would last like 4-5 days without a charge. Today an iphone Barely makes it through a day of use. If you ask me longer battery life is the next step in smartphone evolution rather than more pixels or batter cameras.

All they need is to put a 4000-5000mah battery onto a phone?

Is that really hard?

That has nothing to do with charging. People are worried about phones exploding and batteries not lasting more than 1-2 years.

Here is the video of OPPO demo fully charge a 2500mAh battery in 11 minutes at MWC2016, OPPO say that their superVOOC quick-charging tehnology will work with their micro-USB and USB Type-C connectors soon, it just requres OPPO's special high-Amps 5V charger and with OPPO's special thick charging cable. OPPO already has 4.5Amps fast charging on their current phones, this is the next level and they do not yet announce what the Amps are in this one but they promise that it's safe because it remains at only 5V.

you can compute it yourself:
2500mAh = 2.5Ah
2.5Ah * (60min / 11min) = 13.64Amps
13.64Amps / 0.8 losses = 17Amps

just a little tid-bit, the minimum current to Arc Weld a 0.8mm steel plate is 20 Amps. tongue.gif

Now I just got used to leaving it plugged in to my PC. Takes about 4-5 hours but at least my phone isnt hot after... Doing a quick google search, it does it a 900 mA.

Um, 2A is safe; even Google uses cables specced for 3A for the Nexus. People worry too much about their batteries. The issue with battery life is using the device whilst it's being charged. If the device is idle when charging, battery life is far more sustainable. If OPPO say it's safe, I believe them. I've had the Find 7 with VOOC for a year plus, and also have friends with Qualcomm QC 2.0 devices. No battery degradation thus far. Don't worry and just enjoy the phone for what it is, a device to do stuff on.

I'd personally prefer if VOOC used a 12V standard and a proprietary cable. That way people will be safe and not try and use the VOOC charger with rubbish cables.

Actually I don't like my Find 7's charger that much, the cable is not detachable and I've found that PC's sometimes don't recognise the phone unless it's got the propriety Oppo cable. Fortunately I know someone who lost their Find 7 so they gave me their charger which has a detachable cable.
