The recently launched One Plus 3 phone offers its own patented Dash Charge technology with its 3,000mAh and claims to offer one day’s normal usage with 30 minutes of charging. The Gionee M5 Plus sports a 5,020 mAh battery and claims 47 hours of talk-time and 12 hours of video playback. Another school of thought believes it is better to accelerate the recharge cycle.5 device is more phablet than phone. Dr Gordon Moore had predicted, 50 years ago, that the performance of a semiconductor chip doubles every 18 months. IBM made headlines last year suggesting one could replace the heavy carbon rod with air, except that the normal air we breathe is just not pure enough.

With no radical new battery technology in sight, the best the industry can offer us is one of two options: bigger batteries or a faster way to charge. And at this year’s Mobile World Congress, Oppo unveiled what it called Super VOOC Flash Charge, which charges a PVC Shower curtains Company 2,500 mAh battery in 15 minutes. Phones that run on Qualcomm’s Snapdragon processor can deploy that company’s Quick Charge technology, now into version 3. We will reserve a full throated ‘three cheers’ till batteries become as clever at their job as the phone itself. But it is the battery that fuels your phone — and a pretty lousy job it has been doing — till now.

Batteries remain the top pain point of phone owners, but some relief is comingMobile phone capability seems to mimic Moore’s Law. So it seems, does the power under the hood of your hand phone, with today’s octa-core processor, an eight-fold improvement in five years. These days the bigger battery brigade has gone way beyond the typical 2,000-3,000 mAh of a year ago: By month end Xiaomi will be launching the Mi Max with a jumbo 4850 mAh battery that promises to keep you going for two days; not bad considering this 6. Three years ago Eesha Khare, an Indian-origin student in the US took a top prize at the Intel Science Fair with a Super Capacitor that could charge a phone battery in 30 seconds. We may greet these stop gap solutions with muted applause. Loughborough University is working on fuel cells using hydrogen, which theoretically could power a phone for a week. And consider the technology: it has always been Lithium Ion for a long time, that’s very similar to the Leclanche cell we studied in school, but with a compound of Lithium as the positive electrode, carbon or graphite as the negative pole and a salt of Lithium as the semi fluid in between. Remember the simpler times when your phone did just calls and text messages Once charged, the device was good to go for a week.There’s plenty of talk of new and alternative materials — but mostly they remain talk. Now, the battery in a five or six inch handset with fairly typical multimedia usage won’t last the working day. The Asus Zenfone Max has a 5,000 mAh battery and power saving circuitry that controls processor performance as well as screen brightness to assure at least 2 days on a charge.

The Le Max 2 which is reviewed below, has a 3,100 mAh battery backed by proprietary technology for a very short charge cycle. She is now a student at Harvard and no one knows if she was able to commercially market her brainchild.0, which promises to charge the phone three times faster than with a normal charger
