My daughters new phone Pantech Ease P2020 (bought 4 months ago) is not keeping a charge for very long. We are in a strong signal area (Deerfield, IL 60015) and she makes phone calls rarely (1-2 times a...
Unfortunately, as I myself have discovered, the battery lifeof Pantech Ease is not up to par even for light use. I bought a beautiful used Pantech Ease on-line from Mobile Karmafor 50 dollars and the (used) battery that came with it was verydisappointing. They very promptly sentme another Pantech battery that is about the same as the other one. I had to charge them twice a day unless Iused ATT Navigator GPS, which needed a recharge after only using it for a 20minute drive. Anytime you use a 3Gnetwork for ANY kind of data the drain on the battery is tremendous. The touch screen is also a drain; it isbetter to enter information on the slide out keyboard. Using Bluetooth is also a big drain on thebattery life.I have a background in electricity and electronics and havea good understand on the proper use, charging and maintenance ofbatteries. However, for me, theLithium-Ion is a critter that I was unfamiliar with. Therefore, I turned to the best and most highly technical sourceof battery information I know of and read an article and great discussion foundat battery university.com called "charging lithium ionbatteries" - This is a summary of what I learned there:Li-Ion Batteries do not have a memory like some other typesof batteries, which is a good thing. Therefore there is no advantage to completely discharging thebattery. In fact, it is notrecommended. Luckily there is normallya battery monitoring circuit in the phone that prevents a "complete"discharge of a battery. If these batterieswere ever completely discharged they would not be able to accept a charge froma standard charger. The use of specialcharging equipment would be required to hopefully "revive" thebattery.The best practice for charging and maintaining Li-Ion batteriesis very similar to that of Deep-Cycle batteries. It is best not to drain the battery completely. If the indicator on the phone shows one barremaining, that would be the best time to recharge. Changing through the USB port of a computer is best because it isa slower trickle charge. Most otherchargers are a fast charge. A fastcharge means more heat and heat is an enemy of these batteries. Heat is another reason why it is best torecharge the battery with the phone turned off. When the phone is on it generates a fair amount of heat, whichadds to the heat generated by the charging process. Last but not least to not over-charge or charge for a prolongedperiod of time. The phone notifies youwhen the battery is fully charged even when the phone is off. I have tested, with the phone turned off,and I find the battery does get noticeably warmer if the charger remainsconnected after the battery is shown to be fully charged. Remember, heat is the enemy.If I try do use the phone intensely (i.e. surfing theinternet) when the phone is down to one bar and I have the charger hooked up Iwill soon start receiving notifications from the phone to "CheckBattery". What is happening is I'mdrawing more power from the battery then the charger is able to supply (evenwith the fast charger) and the battery power/charge monitor in the phonenotices the battery is not accepting any charge, which is true. Normally that would mean that battery is badbecause it is not receiving or accepting the power being supplied by thecharger. But in the situation describedI am using more power from the battery then the charger is able toreplace. This is a bad situation. There's a yo-yo effect going on with thebattery at a low state of charge. Again, this situation causes a lot of heat, the enemy.Bottom line, the Pantech Ease battery is not adequate. It is only a 1000mAh at 3.7Wh and shouldhave been at least a 1500mAh at 5Wh. No one makes an extendedbattery for the Pantech Ease so we are stuck with what we have. With both used batteries I have, aftercharging them consistently as described above, I'm getting twice the standbyand talk time from them then when I first received them. However, when I use the GPS I can count ondraining the battery very quickly.My solution has been to purchase a Portable Power Kitmarketed by Energizer that includes a battery that is rated 1000mAh at4Wh. Physically the battery is twice aslarge as the Pantech battery. I boughtit at Walgreen's for $29 dollars. Itcomes in a small zippered case and includes a USB car charger, an AC travelcharger that trickles at only 0.1A (compared with the Pantech AC fast chargerthat puts out 5 times the power), a USB car charger and an 3-way adapter cablethat lets you charge your phone AND the backup battery at the same time. I use the phones' GPS in the car with thephone in a cradle attached to the A/C vent of the car. It is summer now so cold air blows directlyon the phone while the Energizer car charger via the small cable maintains thephone while I'm using the GPS. There'sdefinitely no heat buildup in the battery when I charge this way.The same small cable also allows me to charge the phone fromthe Energizer battery directly. No needto open up the phone and swap out any batteries. Some people carry an extra Pantech Battery but that can be riskybecause the battery contacts are exposed and it's easy to short the batteryagainst something metal (Not Good). You're looking at a dangerous amount ofheat in less than a N.Y. minute.The Energizer battery is as thin as the Pantech battery sois slides easily in the back of the phone case I wear on my belt. I can even use the same cable to charge thephone directly from the Energizer battery while they are both in that phonecase. It doesn't have any exposedcontacts; it has a recessed micro USB connector just like the phone. The Energizer Kit with both chargers,external battery power pack, cables and connectors costs less than any other qualityexternal power pack I have seen and the other power packs are too big to beportable in the same practical way.I'm sure this is way more information than you were lookingfor but as I searched for a solution to this problem I discovered how manyother people are so disappointed with the battery life of the Pantech Ease andalso searching for practical solutions. I sincerely hope this solution is of help to you and to others.
