I have seen quite a few smartphones that was literally destroyed by bad batteries. Those pouch cells sometimes swell so much that will tear phone apart, break screen and back cover. That usually happens when left forgotten for a few months. |

I would not want to charge a lithium battery once a day. But, the cheap Walmart mechanical timers are around $5 - multiple periods with some has period at 15 minutes but cheaper ones are 30 minutes periods (48 mini buttons around the timing wheel). At merely $5 each, you can cascade them affordably. Say if you cascade 2 of them (put them in series), you can get very interesting recharge time table. In its simplest form, say both are 24 hours cycle and 30 minute per period timers, and both are set to be on at 1AM to 1:30AM. The first one (from the wall outlet) is on real-time, but the second one is not on real-time. The second one is only connected for once every day for 30 minutes, so the wheel advances only 30 minutes every 24 hours. So it hits only 1AM to 1:30AM only once every 48 days... All for just around $10, and no tools needed for assembly. (In truth, the wheels/motors are never in perfect sync, one timer may turn faster than the other so you do have to put that into consideration.) --- End quote --- You can get a 7 day digital timer for under $10. Or for even less (in quantity), an ESP8266 based smart plug. |

Keep it between 40-80% charge using the timer trick. Use a standard "slow charger" to keep it from heating up too much. (I only use a fast charger for my tablets since it's still a fairly low charge rate for those.) |
