- Keep it above 50% as far as possible and don’t charge it to 100%Limer writes that going from 100% to flat is harmful to your phone’s battery if you do it too often, although it is wise to do a full discharge about once a month for “calibration”.
- Once it’s done charging, take it offWhen a fully-charged Lithium-ion battery is left on the charger, it is slowly degraded, so watch the battery meter while charging — in fact, take it off before it hits 100%. Limer advises that you should plug your phone in to charge at about 40%, and let it run up to about 80% before taking it off.
- Heat is your phone battery’s worst enemyTry to keep your phone cool, writes Limer, because heat degrades its battery much more quickly, whether it’s being used or not.
- That portable battery pack? It’s bad for your phone tooIn line with the above point about heat, portable battery packs generate a large amount of waste heat, which in turn serves as a toaster for your phone’s battery (!). Best to stick with wall chargers, Limer advises.
