Modern batteries are staying to be one of the biggest problems as for the manufacturers as well as for consumers&period; And it’s not just potential flaming risk&comma; but the slow draining of the source power&period; So it shouldn’t come as a surprise that charging battery on the regular basis makes them work not more than a year or two with active use&comma; after then their capacity is drastically decreasing and using your precious device becomes problematic&period; It’s impossible to completely restore a fully drained battery&comma; but to extend the usage&comma; while looking for new one is quite possible&period; So that’s what we’ll talk about today&period;&NewLine;</p>

The following recommendations are for advanced users&period; So if you can’t make heads or tails of soldering tool it would be better to contact customer service or you could just go straight to local electronic store for a new battery&period;&NewLine;

    Method &numero;1 be useful in cases when battery generates gas due to continuous usage&comma; as a result it gets bulged and can’t hold its charge&period;&NewLine;

    Required tools and materials are&colon; soldering iron&comma; epoxy&comma; fine needle&comma; a heavy flat object for alignment&period;&NewLine;</p>

      &NewLine;
    1. Carefully detach battery case from upper block with sensor&NewLine;</li>
    2. Separate electric sensor&NewLine;</li>
    3. There should be a cap&period; Inside that cap the control electronics is located&period;
      &NewLine;Accurately pierce it with the needle&period; Keep in mind that damaged electric inwards will make following battery restoration impossible&period;&NewLine;</li>
    4. Considering the battery size you should find a heavy flat object witch should be slightly bigger than the battery&period;&NewLine;</li>
    5. Here’s the crucial moment&period; Put the Battery on a table and create some pressure on it with press&period; Note that making to much effort can cause battery to be damaged&comma; as well as making less effort could not give required result&period; It’s strongly recommended not to use any kind of vice or other similar purpose tools&period;&NewLine;</li>
    6. When everything is done put a drop of epoxy on the hole and solder the sensor&NewLine;&NewLine;

      Method &numero;2pletely revive the battery with much reduced resources&comma; but will certainly make it work for some time&period; You shouldn’t count much on it&comma; but it would provide some power for your smartphone&comma; while you’re looking for new battery&period;&NewLine;

      Required tools and materials&colon; any power supply &lpar;5-12V&comma; AC not less than 0&period;1 A&rpar;&comma; voltmeter or tester to monitor the voltage&comma; resistor &lpar;capacity should be at least 500 mWt&comma; resistance of 330 Ohm to 1000 Ohm&rpar;&NewLine;</p>

        &NewLine;
      1. If you don’t have any power supply&comma; it’s ok to use one from your network equipment &lpar;e&period;g&period; switches&comma; routers&comma; modems&rpar;&period; You should be sure that AC options are meet the requirements&period;&NewLine;</li>
      2. Release the contacts from power supply and connect them with drained battery&colon; power supply “minus” with battery “minus”&period; “Plus” line ads with resistor&period; Check the correct polarity with multimeter&period;&NewLine;</li>
      3. When everything is prepared&comma; connect the power supply to the network&period; Procedure should take approximately 2-3 minutes&period; If possible&comma; control process with tester&colon; maximum voltage must not exceed 3&period;3V&NewLine;&NewLine;

        A few important notes&NewLine;

          &NewLine;
        • Do not leave problematic battery unattended&period; The cases of spontaneous ignition is not a theory&comma; but a harsh reality&period;&NewLine;</li>
        • Periodically check the temperature of the battery with the use of bypass thermocouple&comma; electronic thermometer or just by hand&period; If the surface feels to be hot&comma; not just warm&comma; immediately stop repairing&period;&NewLine;</li>
        • Do not use excessive charging currents&period; The maximum you can afford is 50 mAh&period; This parameter is calculated as follows&colon; voltage of power supply divided by the capacitance of the resistor&period; For example&comma; if the first parameter is equal to 12V&comma; and the second is 500 Ohms&comma; the charge current will be equal to 24 mAh&period;&NewLine;</li>
        • Instead of a resistor&comma; you can use a standard 80mm computer fan&period;&NewLine;</li>
        • In order to avoid spontaneous ignition it is recommended to control the initial charging of the restored battery&NewLine;&NewLine;

          Method &numero;3&NewLine;</h2>

          This Metho

          Method &numero;3 and questionable&comma; although according to dedicated forums it helps some users&comma; so the responsibility for any negative consequences lies with you&period;&NewLine;

          Required tools and materials&colon; a working fridge&period;&NewLine;</p>

            &NewLine;
          1. Take the broken battery out of your smartphone and put it in a plastic bag&comma; then the bag must be put in the freezer for 20-30 minutes&NewLine;</li>
          2. Then take it out and put it back in your phone&comma; and start charging for 1 minute&NewLine;</li>
          3. remove it from the device again&comma; let it warm up to room temperature&comma; then charge as usual&period;&period;&NewLine;&NewLine;

            Method &numero;4&NewLine;</h2>

            Innocuous&comma; but les</p>

            Method &numero;4ecovery method&period; But if you think that your smartphone’s battery is ultimately out of order&comma; why not try it&quest;&NewLine;

            Tools and materials required&colon; smartphone with standard battery charger&period;&NewLine;</p>

              &NewLine;
            1. Discharge the battery completely &lpar;up to the stage when the phone can not be switched on&rpar;&period; Any resource-intensive game or AnTuTu utility may prove helpful for this&period;&NewLine;</li>
            2. Fully charge the battery up to the 100&percnt; level&period;&NewLine;</li>
            3. Repeat points 1 and 2 several times&period;&NewLine;&NewLine;

              Method &numero;5&NewLine;</h2>

              Almost all professiona</p>

              Method &numero;5l consider procedures described below a blasphemy&comma; but many users of old batteries have proved this method to be helpful&period;&NewLine;

              NOTICE&colon; I strongly discourage you from using this method unless you have tried other&comma; less risky ones&period;&NewLine;

              Tools and materials required&colon; razor blade&comma; skinny screwdriver&comma; ‘Moment’ glue&period;&NewLine;</p>

                &NewLine;
              1. Retrieve the battery from your phone&period;&NewLine;</li>
              2. Peel off the technical specification label&period;&NewLine;</li>
              3. Remove as much of the top plastic cover&comma; that protects control electronic components&comma; as possible&period;&NewLine;</li>
              4. Find main contact elements&period;&NewLine;</li>
              5. Short-circuit them just for an instant with the help of any metallic object&period;&NewLine;</li>
              6. Glue the top cover back and let the glue dry off&period;I want to draw your attention to the fact that none of the methods above guarantee a 100&percnt; result&comma; and the whole responsibility falls utterly on your shoulders&period; But if the battery shuts off completely and buying a new one is not the prospect of your immediate future&comma; you should try them out&period; In case your rarely find yourself in the process of soldering something and have no head for science&comma; it’s safer to ask a friend who is well-versed in such things&period;&NewLine;&NewLine;
