tablet advice on battery charging
Just purchased my first tablet. Samsung tab A. I am wondering what the best policy is to prolong the battery life.
Should the battery be allowed to run down close to empty and then recharge or should I do top up charging after each session of use. Is it true that worn out batteries cannot be replaced ? |

The only advice is not to let it run completely down. But it doesn't really matter if you do accidentally. It's not usual to be able to replace the battery on a tablet. When the battery fails that's your tablet kaput, unless you're an electronics expert I suppose? |

With lithium chemistry batteries as are used in modern portable devices, there are two rules:
Always fully charge before first use. It will tell you how long to charge it for in the manual. That's the minimum length of time, there is no harm in keeping the device on charge overnight for longer as all lithium battery powered devices have charge circuitry which prevents the battery being overcharged no matter how long it is on charge for. You only need to do that once before first using it. Second, never fully discharge the battery. Most devices will prevent you from fully discharging it as they'll say the battery is dead and shut off before it really is empty, but to be safe, once it is below an indicated 20%, you should really be considering recharging. Unlike nickel chemistry batteries which some people say worked best with a full discharge and recharge each cycle (there is increasing evidence that either wasn't true or certainly isn't true of recent nickel cells), it is generally agreed that lithium batteries work best by only ever being partially discharged and then topped up. In other words, after the first initial full charge, put your tablet on charge again whenever it is convenient. |

An initial charge for several hours is not required.
Nor is it necessary to worry about running the battery down to a very low level. There is a safety buffer built in to prevent accidental over-discharging. Just enjoy your new tablet and charge it as and when you need to. The only real thing to watch out for is excessive heat as the chemistry of lithium batteries can be easily damaged by excessive heat, so don't leave it in direct sunlight and don't put it on to charge under a pillow or cushion or anything like that. |

Thanks guys. Fully charged first time use as advised by maker. So I hope life span of battery is better than laptops.
